Linkers in some versions of binutils 2.25 and 2.26 don't support protected data symbol with error messsage like: /usr/bin/ld: copy reloc against protected `bar' is invalid /usr/bin/ld: failed to set dynamic section sizes: Bad value We check if linker supports copy reloc against protected data symbol to avoid running the test if linker is broken. [BZ #17711] * config.make.in (have-protected-data): New. * configure.ac: Check linker support for protected data symbol. * configure: Regenerated. * elf/Makefile (modules-names): Add tst-protected1moda and tst-protected1modb if $(have-protected-data) is yes. (tests): Add tst-protected1a and tst-protected1b if $(have-protected-data) is yes. ($(objpfx)tst-protected1a): New. ($(objpfx)tst-protected1b): Likewise. (tst-protected1modb.so-no-z-defs): Likewise. * elf/tst-protected1a.c: New file. * elf/tst-protected1b.c: Likewise. * elf/tst-protected1mod.h: Likewise. * elf/tst-protected1moda.c: Likewise. * elf/tst-protected1modb.c: Likewise.
