[PATCH] Dev86 patches

Hi,

These are a few changes in the toolchain to make building old V7 code
for ELKS more comfortable and to build the toolchain with ELKS under
/usr/src/elks without getting some really strange error messages (not
that I think I'll really get somewhere building V7 code in ELKS, but
porting Bourne shell sounded interesting). Repository at
http://helllabs.org/git/dev86.git.

    Run ncc with -ansi to build libc

    When ELKS headers are in place, ncc must be run with -ansi to build
    the C library otherwise a lot of strange errors will be reported
