[compiler-rt][builtins] Define AT_HWCAP2 for AArch64
Without the definition, build fails on AArch64 with > error: 'AT_HWCAP2' undeclared (first use in this function); > did you mean 'AT_HWCAP'? with old Glibc versions. Differential Revision: https://reviews.llvm.org/D145494 (cherry picked from commit 23fcca822a3a3b9a14b6a1ad432814e2634cdb63)
