Abort in elflink.c when building glibc trunk

[Will Newton]

Building glibc trunk from today (but also most likely older ones) results in an abort:

ld: BFD (GNU Binutils for Ubuntu) 2.23.52.20130913 internal error, aborting at ../../bfd/elflink.c line 8826 in elf_link_output_extsym

This looks like it was fixed by this commit:

    Fix references to __ehdr_start when it cannot be defined

    ld/
        * emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
        Don't use bfd_elf_record_link_assignment to mark __ehdr_start
        hidden. Instead, just do it directly here, and only if it was
        referenced but not defined.

    ld/testsuite/
        * ld-elf/ehdr_start-userdef.t: New file.
        * ld-elf/ehdr_start-userdef.d: New file.
        * ld-elf/ehdr_start-strongref.s: New file.
        * ld-elf/ehdr_start-missing.t: New file.
        * ld-elf/ehdr_start-missing.d: New file.
        * ld-elf/ehdr_start-weak.d: New file.
        * ld-mips-elf/ehdr_start-2.nd: Expect __ehdr_start to be global.

The patch is on trunk and the 2.24 branch I believe.
