[ARM] Fix ld.so crash when built using Binutils 2.29
There is bug report that ld.so in GLIBC 2.24 built by Binutils 2.29 will crash on arm-linux-gnueabihf. This is confirmed, and the details is at: https://sourceware.org/bugzilla/show_bug.cgi?id=21725. As analyzed in the PR, the old code was with the assumption that assembler won't set bit0 of thumb function address if it comes from PC-relative instructions and the calculation can be finished during assembling. This assumption however does not hold after PR gas/21458. * sysdeps/arm/dl-machine.h (elf_machine_load_address): Also strip bit 0 of pcrel_address under Thumb mode.
