Patch for configure.in


I tried to run configure with:
--with-headers=/usr/src/linux-2.3.x/include --enable-kernel=2.3.40

But this failed.  The appended patch fixes the bug.  The problem was
that we test with AC_EGREP_CPP - but set CFLAGS instead of CPPFLAGS
:-(.

The patch is only needed for glibc 2.2.  2.1.3 is fine since we use
AC_TRY_COMPILE.

	* sysdeps/unix/sysv/linux/configure.in: Set CPPFLAGS for kernel
	version check since we're using cpp.
