My configure line up until now with the manually added extra-libs:

# ./configure --arch=x86 --target-os=mingw32
--cross-prefix=/cygdrive/m/ffmpeg-windows-build-helpers-master/native_build/windows/ffmpeg_local_builds/sandbox/cross_compilers/mingw-w64-i686/bin/i686-w64-mingw32-

It does. And since we're in the process of fixing the external library
checks in 'configure', I've removed all --extra-libs and --extra-cflags
entries from the configure line and I've made some changes to
'configure' until no more errors showed up.

_Libcaca_

-enabled libcaca           && require_pkg_config libcaca caca caca.h
caca_create_canvas
+enabled libcaca           && require_pkg_config libcaca caca caca.h
caca_create_canvas -DCACA_STATIC && add_cppflags -DCACA_STATIC
(see
https://github.com/Reino17/ffmpeg-windows-build-helpers/blob/master/cross_compile_ffmpeg.sh#L1652-L1653
)

Otherwise you'll get "undefined reference to `_imp__caca_create_canvas'"
and "ERROR: caca not found using pkg-config".

_Libilbc_

My 'libilbc.pc' doesn't include -lpthread at all. Adding it here
manually works for me.

-enabled libilbc           && require libilbc ilbc.h
WebRtcIlbcfix_InitDecode -lilbc
+enabled libilbc           && require_pkg_config libilbc libilbc ilbc.h
WebRtcIlbcfix_InitDecode -lpthread

_Libmodplug_

-enabled libmodplug        && require_pkg_config libmodplug libmodplug
libmodplug/modplug.h ModPlug_Load
+enabled libmodplug        && require_pkg_config libmodplug libmodplug
libmodplug/modplug.h ModPlug_Load -DMODPLUG_STATIC && add_cppflags
-DMODPLUG_STATIC

Although I've replaced libmodplug for libopenmpt, I know FFmpeg's
'configure' needs this. I don't know the "undefined reference"-message
anymore.

_Libopenmpt_

-enabled libopenmpt        && require_pkg_config libopenmpt "libopenmpt
>= 0.2.6557" libopenmpt/libopenmpt.h openmpt_module_create
+enabled libopenmpt        && require_pkg_config libopenmpt "libopenmpt
>= 0.2.6557" libopenmpt/libopenmpt.h openmpt_module_create -lstdc++
-lshlwapi

Adding -lstdc++ fixes the 12000 errors I mentioned earlier, but without
-lshlwapi you'd still get:

/cygdrive/[...]/lib/libmpg123.a(compat.o):compat.c:(.text+0xcb):
undefined reference to `_imp__PathIsRelativeW at 4'
/cygdrive/[...]/lib/libmpg123.a(compat.o):compat.c:(.text+0x224):

/cygdrive/[...]/lib/libmpg123.a(compat.o):compat.c:(.text+0x670):

/cygdrive/[...]/lib/libmpg123.a(compat.o):compat.c:(.text+0x10c4):
undefined reference to `_imp__PathIsUNCW at 4'

_Librubberband_

-enabled librubberband     && require_pkg_config librubberband
"rubberband >= 1.8.1" rubberband/rubberband-c.h rubberband_new
+enabled librubberband     && require_pkg_config librubberband
"rubberband >= 1.8.1" rubberband/rubberband-c.h rubberband_new -lstdc++

Same sort of error-messages as with libopenmpt.

_Libsnappy_

-enabled libsnappy         && require libsnappy snappy-c.h
snappy_compress -lsnappy
+enabled libsnappy         && require libsnappy snappy-c.h
snappy_compress -lsnappy -lstdc++

Same sort of error-messages as with libopenmpt.

_Libtwolame_

-enabled libtwolame        && require libtwolame twolame.h twolame_init
-ltwolame &&
+enabled libtwolame        && require libtwolame twolame.h twolame_init
-ltwolame -DLIBTWOLAME_STATIC && add_cppflags -DLIBTWOLAME_STATIC &&

Otherwise you'll get "undefined reference to `_imp__twolame_init'" and
"ERROR: libtwolame not found".

_Libzvbi_

-enabled libzvbi           && require libzvbi libzvbi.h vbi_decoder_new
-lzvbi &&
+enabled libzvbi           && require_pkg_config libzvbi zvbi-0.2
libzvbi.h vbi_decoder_new &&

Otherwise you'll get lots of "undefined reference to
`pthread_mutex_[...]'" errors.

zvbi-0.2.pc:

prefix=/cygdrive/[...]
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: ZVBI
Description: VBI Capturing and Decoding Library
Requires:
Version: 0.2.35
Libs: -L${libdir} -lzvbi -lm -lpthread -lwsock32  -lpthread  -lm -liconv
Cflags: -I${includedir}

This way all the libraries get loaded, including -lpthread.

And this works. No more errors during ./configure, but then...
