it is not ideal that both musl and gcc headers get
included with the typedefs, but i don't see why
they are in conflict:
both typedefs should expand to 'unsigned long'
(if not then something is very wrong)
you can try to rerun that build command with -E
instead of -c to see the actual size_t definitions
after macro expansion.
(i assume multilib breaks it somehow, but i don't
see how)
