Have now moved this on by running ./configure with the options previously
advised, and then editing two of the files it creates as follows:
Replace 0s with 1s in the following ...
#define HAVE_FMINF 0
#define HAVE_LRINT 0
#define HAVE_LRINTF 0
#define HAVE_ROUND 0
#define HAVE_ROUNDF 0
#define HAVE_TRUNC 0
#define HAVE_TRUNCF 0
Remove the leading !s in the following ...
This started off the compile in grand styls, but it eventually fails as
libavcodec/mips/aacsbr_mips.h: In function 'sbr_qmf_synthesis_mips':
libavcodec/mips/aacsbr_mips.h:199: error: can't find a register in class
'FP_REGS' while reloading 'asm'
make: *** [libavcodec/aacsbr.o] Error 1
