libomp should be built for both i386 and x86_64

[howarth.at.macports@…]

The attached Portfile diff updates libomp to the r248588 to pick up the new lit-based test suite support for running 'check-libomp' as well as appends -DLIBOMP_OSX_ARCHITECTURES="x86_64;i386" to the cmake flags to build the fat libomp supporting both i386 and x86_64 targets.

update to lit-based test suite support and build i386/x86_64 fat libomp

Note that the OpenMP3.1_Validation results for 'make ctest' are reasonable using the proposed libomp packaging and clang-3.7. at -m64...

A port should only build universally if the universal variant is selected. If a universal build is required, that can be enforced by adding the line "default_variants +universal", but that would be somewhat unusual.

[eborisch (Eric A. Borisch)]

It should build universal with +universal already. I will look at the rest of this soon.

[eborisch (Eric A. Borisch)]

Committed new version in r140675. No changes for universal (works with +universal.)
