Ok, this fixed the bootstrap fail, but make check showed the following
regressions:

FAIL: gcc.c-torture/execute/950503-1.c execution,  -O1 
FAIL: gcc.c-torture/execute/950503-1.c execution,  -O2

and during compile I got the following unusual warning:
fp-bit.c: In function `__pack_f':
fp-bit.c:542: warning: Subreg here

Additionally your patch seems to fix Geoff's pet bug ;-) asm("" : : :
"cc"), which now compiles just fine (also part of the configure tests of
glibc-2.0.95).
Seems to me you are on the right track.

Thanks for the good work,
Franz.
