           Summary: [4.6 Regression] Multiple test suite failures due to

           Version: 4.6.0

Revision 170321 caused a lot of failures on the test suite on
x86_64-apple-darwin10 and moxie-unknown-elf (see
http://gcc.gnu.org/ml/gcc-testresults/2011-02/msg02205.html). They are all of
the form:

[macbook] f90/bug% gcc46
/opt/gcc/work/gcc/testsuite/gcc.c-torture/execute/builtins/20010124-1.c
/opt/gcc/work/gcc/testsuite/gcc.c-torture/execute/builtins/20010124-1-lib.c
/opt/gcc/work/gcc/testsuite/gcc.c-torture/execute/builtins/lib/main.c -flto
lto1: fatal error: target specific builtin not available
compilation terminated.
lto-wrapper: gcc46 returned 1 exit status
collect2: lto-wrapper returned 1 exit status

Reverting the revision fixes the failures.

This is pr seems related to pr47820.
