indeed, the check_cpu_feature() function is defined in 
src/utils/x86_asm/cpuid.asm [1] which includes src/nasm.inc, which in 
turn declares a .rotext section [2] for any other output format than 
macho32 and macho64.

It would probably be the best patch this to simply declare a .text 
section for all output formats. The question remains, however, why this 
is an issue now but not when xvidcore_2:1.3.5-1 was uploaded?
