uClibc on Coldfire (m68k) compile problems

[Jim Burnett]

Fresh binutils-2.19 build (Just re-ran make install to get /opt/embedded
fresh)

export PATH=/opt/embedded:$PATH

Then configured gcc just like I did with the older version that compiled
just fine.

./configure --target=m68k-uclinux --prefix=/opt/embedded
--enable-languages=c

make

Then this error.

Checking multilib configuration for libgcc...
make[2]: Entering directory
`/home/jim/Newdev/toolchains/gcc-4.3.3/m68k-uclinux/libgcc'
Makefile:144: ../.././gcc/libgcc.mvars: No such file or directory
make[2]: *** No rule to make target `../.././gcc/libgcc.mvars'.  Stop.
make[2]: Leaving directory

Using  binutils-2.19



My Comp Specs:
[jim at myhost bin]$ gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../configure --prefix=/usr --enable-shared
--enable-languages=c,c++,fortran,objc,obj-c++,ada --enable-threads=posix
--mandir=/usr/share/man --infodir=/usr/share/info --enable-__cxa_atexit
--disable-multilib --libdir=/usr/lib --libexecdir=/usr/lib
--enable-clocale=gnu --disable-libstdcxx-pch --with-tune=generic
Thread model: posix
gcc version 4.4.3 (GCC)

[jim at myhost bin]$ uname -r
2.6.32-ARCH




Still working on it, just wanted to send an update to anyone that is
following.
