Add localplt.data for sh. This patch adds a localplt.data file for sh so that test passes. The architecture-specific entries are for _Unwind_Find_FDE, _exit and __errno_location. Tested for sh3 and sh4. * sysdeps/unix/sysv/linux/sh/localplt.data: New file. 2016-11-08 23:43:17 +00:00			`# See scripts/check-localplt.awk for how this file is processed.`

Allow abort PLT references in libc.so for SH. Given my patch <https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00965.html> for the ICEs building a glibc string function test for SH, the testsuite can build completely for SH with GCC 7 and mainline. However, there is a test failure that does not appear for GCC 6: check-localplt fails because of an abort PLT reference in libc.so. Given the lack of a trap insn pattern for SH, it seems unavoidable that the compiler might sometimes generate abort calls, and such abort calls (generated from __builtin_trap when there is no trap insn pattern) will be unaffected by the normal mapping to __GI_abort for calls within glibc. Thus, this patch allows (but does not require) an abort PLT reference in libc.so for SH. Tested for sh4-linux-gnu with build-many-glibcs.py (GCC 7, with my patch applied). * sysdeps/unix/sysv/linux/sh/localplt.data: Allow abort in libc.so. 2017-08-16 17:01:27 +00:00			`# Generated by the compiler because there is no trap insn pattern.`
