    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.
