libgcc, i386: Export *hf* and *hc* from libgcc_s.so.1

The following patch exports it for Linux from config/i386/*.ver where it
IMNSHO belongs, aarch64 already exports some of those at GCC_11* and other
targets might add them at completely different gcc versions.

	* config/i386/libgcc-glibc.ver: Add %inherit GCC_12.0.0 GCC_7.0.0
	and export *hf* and *hc* functions at GCC_12.0.0.
