crosstool-0.28-pre7: cygwin, macosx compatibility

[Dan Kegel <dank at kegel dot com>]

I've integrated the cygwin and macosx compatibility patches,
so crosstool should build there now.  I've tried it on
cygwin, still haven't tried on macosx.  Please give it a shot
and let me know how it goes.

This is not really a release of crosstool, just a snapshot for
testing.

Changelog:

0.28-pre7 14 Mar 2004
     gcc/glibc versions:
     * support gcc-3.3.3
     * support glibc-2.1.3 for you redhat 6.2 fans
     * Added patches/glibc-2.1.3/glibc-2.1.3-allow-gcc3-*.patch
       to allow compiling glibc-2.1.3 with gcc-3.x

     cygwin compatibility:
     * patch glibc to not depend on case sensitivity:
       patches/glibc-2.2.5/glibc-2.2-cygin-shared.patch
       patches/glibc-2.3.2/glibc-2.3.2-cygwin-shared.patch
     * demo*.sh: don't use ~, as ash doesn't expand it
     * getandpatch.sh: don't use set -e when calling functions that return 1

     MacOS/X compatibility (thanks to Martin Schaffner):
     * patches/linux-2.4.24/linux-2.4-bsd-expr.patch
     * patches/glibc-2.3.2/glibc-configure-apple-as.patch

     arm:
     * Revert to binutils-2.14.90.0.5 because arm has trouble with plain 2.14
     * copied gcc-3.3.2-arm-softfloat.patch to patches/gcc-3.3.3,
       but probably still need contrib/glibc-vfp.patch
       Added more notes to demo-arm-softfloat.sh
     * Added arm-iwmmxt

     getandpatch.sh (thanks to Alan Luse):
     * use BASENAME in test for previously extracted source trees
     * don't cd to nonexistent patch directories
     * Handle linux tarballs which extract to directory 'kernel'
     * Added a QUIET_EXTRACTIONS option to do non-verbose extractions

     crosstool.sh:
     * On exit, say *where* the result was stored
     * Verify that LD_LIBRARY_PATH is not set, since glibc complains if set

     demo.sh:
     * updated to use gcc-3.3.3 where possible
     * created demo-$CPU.sh scripts for more processors
     * demo.sh now just calls all the demo-$CPU.sh scripts
     * demo.sh now runs through all cpu types even if one fails,
       and makes separate log files for each
     * added mkcommon.sh to compile distcc, tcl, expect, dejagnu

     Regression test changes:
     * Added demo-runtest.sh as example of how to run a single regression test
