error installing glibc headers using crosstool-0.25

[Robert P. J. Day]

  (note: i originally asked some preliminary questions about crosstool
on the etux list, but i'm pretty sure this is the more appropriate forum,
yes?)

  i'm trying to build a powerpc toolchain using:

	gcc-3.3.2
	glibc-2.3.2
	binuitils-2.14.90.0.5
	linux-2.4.21

i started with dan's crosstool-0.25, hacked up the main script for
reasons we don't need to get into, and started the build.  the
starting point, in terms of variables, was

  ARCH = ppc
  TARGET = powerpc-750-linux-gnu
  BUILD_DIR = /embedded/ct/build
  PREFIX = /embedded/ct/result/powerpc-750-linux-gnu/gcc-3.3.2-glibc-2.3.2
  BUILD = i686-pc-linux-gnu
  HOST = i686-host_pc-linux-gnu

the build got into the step of installing glibc headers, then in the midst
of *much* output, i got numerous errors of the form (line breaks added for
formatting):

cc1: error: invalid option `new-mnemonics'

...

  there are dozens of these errors.  am i somehow setting the wrong 
variable values to represent a PowerPC-based toolchain?

  and even with all these errors, this step completes, the building of 
gcc-core completes as well, then the build of glibc itself fails with a
couple of the exact same errors.

cc1: error: invalid option `powerpc'
cc1: error: invalid option `new-mnemonics'

make[1]: *** [csu/subdir_lib] Error 2
make[1]: Leaving directory `/embedded/ct/patched/glibc-2.3.2'

  hints?  suggestions?
