uml: fx command-line CFLAGS and LDFLAGS support
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.
