Bugzilla Bug 99456

all seems well until make-target-2.sh gets executed:

//entering make-target-2.sh
//doing warm init
make-target-2.sh: line 99: 24787 Illegal instruction     ./src/runtime/sbcl
--core output/cold-sbcl.core --sysinit /dev/null --userinit /dev/null  <<-'EOF'


Reproducible: Always
Steps to Reproduce:
1. echo "=dev-lisp/sbcl-0.9.2 ~ppc" >> /etc/portage/package.keywords 
2. emerge sbcl
3. emerge fails

Actual Results:  
emerge of sbcl-0.9.2 fails

Expected Results:  
emerge of sbcl-0.9.2 succeeds

This is probably a long shot, but does the outcome change if you replace your
CFLAGS with just CFLAGS="-pipe"?  Failing that, SBCL 0.9.3 will be in the tree
shortly so we can try to reproduce it against that as well.

CFLAGS="-pipe" emerge =dev-lisp/sbcl-0.9.2

Result: 

//entering make-target-2.sh
//doing warm init
make-target-2.sh: line 99:  7412 Illegal instruction     ./src/runtime/sbcl
--core output/cold-sbcl.core --sysinit /dev/null --userinit /dev/null  <<-'EOF'

Could you please try sbcl 0.9.4 which has just been placed in portage? 

Someone else confirmed that sbcl-0.9.4 builds on ppc.
