Just ignore this (see below for my "fix").

These are new system calls, which means you need a new libc as well.
So you first need to go to /usr/src/lib/libc and do a "make && make
install" there.  It also probably wouldn't hurt to build and install the
new csu (C Start Up?) files in /usr/src/lib/csu _before_ libc too.

For what it's worth, on my slower machines I usually do the following

	make NOMAN= NOLINT= NOPROFILE=

which doesn't build man pages, lint checks and profiled libraries.  Much
faster :-)

And always backup your libraries before installing new ones!
