[ 2.6.25 material ]
UML still needed some work in order to allow CFLAGS to be passed in
from the command line.
USER_CFLAGS is produced from KBUILD_CFLAGS in part by removing all the
-I switches. This is so that kernel headers don't accidentally get
pulled into libc files. However, a common use of command-line CFLAGS
would be to add -I switches to the build. This patch specifically
adds any command-line -I flags back to USER_CFLAGS.
I also corrected the spelling of LFLAGS to LDFLAGS.
