I wouldn't mind a patch which did that, even if it meant adding a line for
every file which did that.
I'm not a preprocessor wizard but couldn't you hide all that in a macro,
like:

INIT_ARCH_CODEPATH(ARCH_X86, ff_aac_dsp_init_x86(s)))

if you define the macro in config.h somehow such that the preprocessor
doesn't evaluate whether ARCH_X86 is defined?
