i386: Do not set internal_function
All calls to functions with the internal_function attribute
have been removed from assembler implementations, which means that
the definition of internal_function can be changed at the C level
without causing ABI issues with assembler code.
_dl_fixup still uses a regparm calling convention on i386, but this
is controlled through ARCH_FIXUP_ATTRIBUTE, not internal_function.
