[Clfs-support] Assembler error when making target 'all-target-libgcc' with the 'thumb' ARM mode

[Andrew Bradford]

As a funny aside, while trying to reproduce your uClibc issue, I got
all mixed up with variables and ended up reproducing this issue.  Good
to know it's confirmed... but not really what I was trying to do.

The all caps define __GCC_FLOAT_NOT_NEEDED looks interesting though
for your other issue....
I'll reply to the other thread with my findings once I straighten out
my variables.

My failure ends like this for building libgcc the way you are:
