    aclocal.m4: drop obsolete -fno-stack-protector · 29ecb520

    Summary:
    Initially -fno-stack-protector was added for openbsd specifically for ghc-6.5:
        changeset:f638fdfe (2006)
    and later it was extended to cover osx:
        changeset:c2cd83e7 (2009)
    
    None of the reports hint at exact breakage. I guess both happened
    in -fvia-C mode where GHC's Evil Mangler had a chance to mangle
    stack canaries generated by fstack-protector.
    
    ghc has no evil mangler anymore and the change is not needed
    at least for C codegen.
    
    validated the patch on OpenBSD-6.4. No new failures compared to
    clean master branch.
