Rebased, and dropped the false ChangeLog update. Thanks, Florian 8<------------------------------------------------------------------8< MIPS needs to ignore certain existing symbols during symbol lookup. The old scheme uses the ELF_MACHINE_SYM_NO_MATCH macro, with an inline function, within its own header, with a sysdeps override for MIPS. This allows re-use of the function from another file (without having to include <dl-machine.h> or providing the default definition for ELF_MACHINE_SYM_NO_MATCH). Built with build-many-glibcs.py, with manual verification that sysdeps/mips/elf_machine_sym_no_match.h is picked up on MIPS.

Oh, good point. New version below. Thanks, Florian 8<------------------------------------------------------------------8< MIPS needs to ignore certain existing symbols during symbol lookup. The old scheme uses the ELF_MACHINE_SYM_NO_MATCH macro. This commit replaces it with an inline function, elf_machine_sym_no_match, within its own header. It ads a sysdeps override for MIPS to implement the desired functionality there.
