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.

+
+ i386: Do not set internal_function.
+ * config.h.in (USE_REGPARMS, internal_function): Remove.
+ * sysdeps/i386/configure.ac (USE_REGPARMS): Likewise.
+ * sysdeps/i386/configure (USE_REGPARMS): Likewise.

* elf/dl-init.c (_dl_init): Remove internal_function.
