[llvm-readelf] - Remove the precompiled binary from gnu-hash-symbols.test
I am working on https://bugs.llvm.org/show_bug.cgi?id=42622 and this patch reworks the gnu-hash-symbols.test so that it will be easier to expand it with x86_64 case. Differential revision: https://reviews.llvm.org/D64750 llvm-svn: 366430
