Disable R_X86_64_PLT32 generation as branch marker on Solaris/x86
The fix H.J. implemented for PR gas/22791 in the thread starting at [PATCH] x86-64: Treat PC32 relocation with branch as PLT32 https://sourceware.org/ml/binutils/2018-02/msg00065.html is causing problems on Solaris/x86. The native linker is strongly preferred there, and there's no intention of implementing the linker optimization he plans there. Besides, the kernel runtime linker, otherwise has no need to deal with that reloc at all, and instead of adding (possibly even more) workarounds with no benefit, it seems appropriate to disable the R_X86_64_PLT32 generation as branch marker on Solaris/x86 in the first place. The patch itself is trivial, the only complication is adapting the testsuite. Since I've found no way to have conditional sections in the .d files, I've instead used the solution already found elsewhere of having separate .d files for the affected tests in an i386/solaris subdirectory and skipping the original ones. Tested on amd64-pc-solaris2.11 and x86_64-pc-linux-gnu without regressions. * config/tc-i386.c (need_plt32_p) [TE_SOLARIS]: Return FALSE. * testsuite/gas/i386/solaris/solaris.exp: New driver. * testsuite/gas/i386/solaris/reloc64.d, testsuite/gas/i386/solaris/x86-64-jump.d, testsuite/gas/i386/solaris/x86-64-mpx-branch-1.d, testsuite/gas/i386/solaris/x86-64-mpx-branch-2.d, testsuite/gas/i386/solaris/x86-64-nop-3.d, testsuite/gas/i386/solaris/x86-64-nop-4.d, testsuite/gas/i386/solaris/x86-64-nop-5.d, testsuite/gas/i386/solaris/x86-64-relax-2.d, testsuite/gas/i386/solaris/x86-64-relax-3.d: New tests. * testsuite/gas/i386/reloc64.d, testsuite/gas/i386/x86-64-jump.d, testsuite/gas/i386/x86-64-mpx-branch-1.d, testsuite/gas/i386/x86-64-mpx-branch-2.d, testsuite/gas/i386/x86-64-nop-3.d, testsuite/gas/i386/x86-64-nop-4.d, testsuite/gas/i386/x86-64-nop-5.d, testsuite/gas/i386/x86-64-relax-2.d, testsuite/gas/i386/x86-64-relax-3.d: Skip on *-*-solaris*.
