The only port that needed a build patch was gworkspace.
no runtime startup issues observed anymore, as it was before
with older lld versions.
Triggered to look at it again by an initial patch from Brad Smith
minor tweask and testing by myself, bump all ports using
gnustep.port.mk
switching to clang in base.
add COMPILER_LIBCXX where c++abi is used. there will be some "Extra"s but
this is the simplest way to use c++abi on base=clang and estdc++ on base=gcc
arches.
macppc still stays on using gcc due to too many problems there.
On amd64 and i386 now use the non-fragile-abi.
Now that allows on amd64 and i386 to use newer objective-c 2.0
features.
