Could you be so kind and point me into direction where the check is made?
Anyway, greping thorough sources for "weakref" and thorough build 
directory I've found this (in build dir):

$ find . -name 'config*' -exec grep "weakref" \{} \; -print
configure:13473: checking assembler for .weakref
conftest.s:1: Error: unknown pseudo-op: `.weakref'
         .weakref foobar, barfnot
gcc_cv_as_weakref=no
./gcc/config.log
gcc_cv_as_weakref=${gcc_cv_as_weakref=no}
./gcc/config.cache
configure:13473: checking assembler for .weakref
conftest.s:1: Error: unknown pseudo-op: `.weakref'
         .weakref foobar, barfnot
gcc_cv_as_weakref=no
./prev-gcc/config.log
gcc_cv_as_weakref=${gcc_cv_as_weakref=no}
./prev-gcc/config.cache
configure:13473: checking assembler for .weakref
conftest.s:1: Error: unknown pseudo-op: `.weakref'
         .weakref foobar, barfnot
gcc_cv_as_weakref=no
./stage1-gcc/config.log
gcc_cv_as_weakref=${gcc_cv_as_weakref=no}
./stage1-gcc/config.cache
$

which seems to me .weakref is not supported by assembler. I've tried to 
syntetize back the test case and got this:

$ cat /tmp/weakref.s
         .weakref foobar, barfnot

$ as /tmp/weakref.s
/tmp/weakref.s: Assembler messages:
/tmp/weakref.s:1: Error: unknown pseudo-op: `.weakref'
$ as --version

It's interesting it's working in gcc then...
