Fix gcconfig to turn on POSIX fork() support by default
(define HANDLE_FORK on Unix platforms with pthreads)
* doc/README.macros (HANDLE_FORK): Replace with NO_HANDLE_FORK; update
the documentation.
* include/private/gcconfig.h (HANDLE_FORK): Explicitly define if
GC_PTHREADS unless already defined or NO_HANDLE_FORK is defined, or
unsupported on the target.
