Ebuild for the libdispatch

libdispatch is a relatively recent development for managing events and concurrency on sub-thread level.

More information can be found here:

Attached ebuild is for the multi platform "xdispatch" fork of the original Apple code:

Work around reserved identifier in glibc's unistd.h

This old and well known problem results from inability of glibc and clang developers to reach a (no brainer) agreement on who is responsible for cleaning out conflicting identifiers in the system headers (long fixed in eglibc).

There's one remaining problem when "clang" flag is set, namely support for __float128 data type. For now, it can be disabled with a conditional macro in a c++-config.h gcc header on per installation basis, but clang support for this data type is in the works.
