crosstool-0.28-rc7: better gcc-3.4.0 support, parallel make

[Dan Kegel <dank at kegel dot com>]

A new snapshot is online at
  http://kegel.com/crosstool/crosstool-0.28-rc7.tar.gz

Still problems with m68k and sparc64, and with cygwin.  I'm unlikely
to dig into those anytime soon; if you're interested in helping,
please do.

Changelog:

0.28-rc7:
     crosstool.sh:
     * when building gcc, don't parallelize install, as that seems to be broken
     * Added new environment variable GLIBC_EXTRA_CC_ARGS because there seems to be no way
       to get gcc to default to 64 bits on sparc64; setting GLIBC_EXTRA_CC_ARGS to e.g. "-64" helps

     arm:
     * fixed typo in arm9tdmi.dat

     sparc:
     * sparc64.dat now makes gcc default to ultrasparc3 to get around glibc compile failure on .S files;
       probably could also have worked around it by setting something like AS_OPTIONS, but didn't explore that
     * updated sparc64.dat to use GLIBC_EXTRA_CC_ARGS to get around glibc link failure (glibc's configury
       doesn't provide any way to pass options to gcc when linking some files!)
       Still can't build glibc-2.3.2 for sparc64; error is
       qp_qtoi.s:261: Error: Illegal operands: There are only 32 single precision f registers; [0-31]

     powerpc:
     * added patches/glibc-2.3.2/glibc-2.3.2-allow-gcc-3.4-inline.patch from cvs to allow building with gcc-3.4.0

     m68k:
     * Still can't build a gcc-3.4.0-glibc-2.3.2 toolchain; error is
       localealias.s:544: Error: junk at end of line, first unrecognized character is `,'
