Convert another .s file to .c - patch courtesy of Gert Vervoort

Support cross compiling for x86_64

Typo. Put closing '}' in right place.

Got tired of seeing the warning message:
y4munsharp.c:77: warning: return type defaults to `int'

Fix
y4mspatialfilter.c:217: warning: int format, size_t arg (arg 2)
gmake[2]: *** [y4mspatialfilter-y4mspatialfilter.o] Error 1

jpeg2yuv.c:422: warning: long int format, int arg (arg 3)
jpeg2yuv.c:435: warning: long int format, int arg (arg 3)
jpeg2yuv.c:449: warning: long int format, int arg (arg 3)
errors. The routines where jpegsize is used are expecting 'int' so use 'int'
and '%d' instead of 'size_t' + "%ul".

Need to ifdef system_error because the only references to it are inside
HAVE_SOUNDCARD_H and that's not defined on OS/X

Unused variables cause compiling to cease when -Werror is used :(

abs() is in stdlib.h instead of math.h (sheesh, what a weird place to put a math function!)
