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.
