Subject: Define empty variables in case no names are added to them. This
 avoids substitution errors for variables that don't exist.

If a machine architecture dependent makefile exists, include it
to discover if libc or libc_r is being built with NetBSD syscalls
instead of FreeBSD ones.

Put a NO_QUAD thingy around the quad makefile so that 64-bit
architectures can ignore that sh*t.

In the test for MDSRCS being empty, add all MISRCS to SRCS, rather
than just ignoring them.
