Add STB_SECONDARY support to ld.sohjl/secondary/2.21
Enable STB_SECONDARY if it is supported by binutils. Add 3 STB_SECONDARY
tests.
* config.h.in: Add HAVE_ASM_SECONDARY_DIRECTIVE.
* config.make.in (have-secondary): New macro.
* configure.in: Check if STB_SECONDARY is supported by as/ld.
Define HAVE_ASM_SECONDARY_DIRECTIVE and set have-secondary to yes
if the .secondary assembly directive works.
* configure: Regenerated.
* elf/Makefile (tests): Add tst-secondary1 tst-secondary2
tst-secondary3 if STB_SECONDARY is supported by as/ld.
(modules-names): Add tst-secondarymod tst-secondary1mod
tst-secondary2mod tst-secondary3mod if STB_SECONDARY is supported
by as/ld.
(LDFLAGS-tst-secondarymod.so): New macro.
($(objpfx)tst-secondary1): New rule.
($(objpfx)tst-secondary2): Likewise.
($(objpfx)tst-secondary3): Likewise.
* elf/dl-addr.c (determine_info): Also check STB_SECONDARY.
* elf/dl-lookup.c (do_lookup_x): Handle STB_SECONDARY.
(_dl_lookup_symbol_x): Likewise.
* elf/sprof.c (read_symbols): Likewise.
* elf/elf.h (STB_SECONDARY): New.
(STB_NUM): Updated.
* elf/tst-secondary.h: New file.
* elf/tst-secondary1.c: Likewise.
* elf/tst-secondary1mod.c: Likewise.
* elf/tst-secondary2.c: Likewise.
* elf/tst-secondary2mod.c: Likewise.
