[FFmpeg-devel] [Patch] vhook and darwin link fix

[SciFi]

Hi,

I'm having to use this patch to get around invalid ldflags when
darwin's linker is used for vhook w/ --enabled-shared :

fwiw my ./configure is letting vhook be enabled by default,
but I do specify --enable-shared for other reasons ...
somehow the -rdynamic and -export-dynamic naked checks by
themselves are passing during ./configure even for darwin, but
during actual link-time of the vhook modules there are other
options specified for darwin that render them invalid in the
actual context found there-in, if that makes any sense... ;)
anyway, not checking for these flags during configure & if
darwin, does fix the link-time problems when wanting shared
module forms.
