Similarly to https://bugs.gentoo.org/show_bug.cgi?id=568698, the fix is stripping the architecture from CFLAGS.
Github pull request (https://github.com/gentoo/gentoo/pull/534).
stripping all flags looks overkill. It's known that pypy certainly compiling with generic and not too-optimized flags, it's better to avoid (filter) the ones that known to break pypy.
Michał also mentioned that stripping ALL flags would break things in the github pull request. The issue with the pypy builds is that architectures other than the compiler default will often result in a compile failure. Using strip-flags doesn't normalize to a common architecture, so defaulting to the pypy compile/link options without custom-cflags seemed fairly reasonable. Explicitly specifying x86-64 is incorrect, since there are a number of other common instruction sets (x86, ARM, SPARC, POWER, etc...). Although, specifying generic is also potentially incorrect given people may be using distcc (which could result in a runtime failure). Using shadowstack as a default may avoid compile issues, but as far as I know asmgcroot is currently the default for linux as per pypy (see asmgcroot http://pypy.org/download.html). There is a potential performance cost to shadowstack as well. Suggestions?
