[bug-libsigsegv] x86_64-apple-darwin17.4.0

[Jon Styles]

trying to: ./configure --prefix=${prefix}   && make && make check && make install

libsigsegv-2.12  on Mac OS X 10.13.3

fails with:

checking build system type... Invalid configuration `2/tools/x86_64-apple-darwin17.4.0': machine `2/tools/x86_64-apple' not recognized

configure: error: /bin/sh build-aux/config.sub 2/tools/x86_64-apple-darwin17.4.0 failed 

Darwin 17.4.0 is the current version of OS X kernel

the error is from line 1571 of build-aux/config.sub 2

tried adding a —host=apple-darwin17.4.0 option to configure with no change ( if that’s the right way to specify the option ??)

thanks
