This patch includes the required modifications (summarized
in common/lib/libc/minix-port.patch) to make the common
part of the NetBSD libc to compile and work under Minix.
This patch imports the unmodified current version of NetBSD libc.
The NetBSD includes are in /nbsd_include, while the libc code itself is
split between lib/nbsd_libc and common/lib/libc.
