Fix the buildbot. test/elf2/gnu-hash-table.s requires ppc target support to run. llvm-svn: 251002

# REQUIRES: x86,ppc
[ELF2] Add support for GNU Hash section This patch implements --hash-style command line switch. * By default, or with "sysv" or "both" parameters, the linker generates a standard ELF hash section. * With "gnu" or "both", it produces a GNU-style hash section. That section requires the symbols in the dynamic symbol table section, which are referenced in the GNU hash section, to be placed after not hashed ones and to be sorted to correspond the order of hash buckets in the GNU Hash section. The division function, as well as estimations for the section's parameters, are just the first rough attempt and the subjects for further adjustments.

Revert "ELF: Make .note.GNU-stack more compatible with traditional linkers." This reverts commit r253797 because it was based on a misunderstanding that lld wouldn't work on NetBSD without this change. llvm-svn: 254003
