[Bug libc/7048] New: glibc-2.9 doesn't build on i{345}86.

["pluto at agmk dot net" <sourceware-bugzilla at sourceware dot org>]

the final link of the ld.so on i486 ends with an error:

glibc-2.9/builddir/elf/librtld.os: In function `_dl_tlsdesc_dynamic':
glibc-2.9/elf/../sysdeps/i386/dl-tlsdesc.S:131: undefined reference to
`__i686.get_pc_thunk.bx'

in sysdeps/i386/dl-tlsdesc.S there's is a thunk call w/o definition.

        call        __i686.get_pc_thunk.bx
        addl        $_GLOBAL_OFFSET_TABLE_, %ebx

the LOAD_PIC_REG(bx) macro fixes link failure.
