[Ltib] Building GCC 4.x for MPC8548

[Davis, Scott (AGRE)]

I decided to use crosstool-0.42 with gcc-4.1.0-glibc-2.3.6.dat.  My ultimate goal is to build Ada compiler for MPC8548 with the double precision hardware floating point extended instruction set.  I tried using the LTIB src rpm but the build fails when trying to build gnat-crosstools.  It appears as if the build is trying to use my host native Ada library files instead of the gcc/ada in the gcc-3_4 tar ball that is apart of the Freescale src rpm.

Now I am ssing crosstools and setup above it fails as well even though I am using gcc-4.x+ which should have the 8548 extensions built-in or at least can build them into gcc

The build fails as follows:
Checking for suffix of object files... Configure: error: can not compute suffix of objecs files: cannot compile See `config.log` for more details.

The root of the problem is from what I figured out is below:
I configure crosstools with in a .dat file with
EXTRA_TARGET_CFLAGS="-mcpu=8548 -mhard-float -mfloat-gprs=double" and mcpu is bad as well and this is the problem that causes the build to fail.  I am using gcc-4.1.0 and glibc-2.3.6 which I believe should work from previous emails. 

The config.log in build-glibc states that -mfloat-gprs=double is an invalid option
and bad value (8548) for -mcpu=switch

Any help on this one.  I realize this is not a crosstools mailing list but I was wondering if you ran into this problem building LTIB gcc toolchains with crosstools.
