mjpegtools: fix build on powerpc without altivec
mpjegtools fails to build on powerpc without altivec:
build_sub44_mests.c: In function 'build_sub44_mests_altivec':
build_sub44_mests.c:268:9: internal compiler error: Segmentation fault
vr1 = vec_ld(rowstride, (unsigned char*)s44blk);
It seems mpjegtools is wrongly detecting altivec support:
configure: - PowerPC Optimizations:
configure: - AltiVec enabled : true
Fix this by adding BR2_PACKAGE_MJPEGTOOLS_SIMD_SUPPORT and setting
--enable-simd-accel / --disable-simd-accel
Fixes:
