[SPEC2017] Use -fno-strict-aliasing when compiling 502.gcc_r, 505.mcf_r

As suggested on SPEC's documentation page (Known Portability Issues) [1][2]
the spec_qsort.c routine does not strictly obey the ANSI aliasing rules.
In the absence of -fno-strict-aliasing the test suite fails when Function
Specialization is enabled with both LTO and PGO
(see https://reviews.llvm.org/D140210).
