Followup to gcc-3 bugreport on Hurd

[Jeff Bailey]

When I harcoded:

libc_cv_gcc_unwind_find_fde=yes

in sysdeps/mach/hurd/configure, the compile worked and produced a
usable glibc (for shared libraries.  I'm still hunting down my static
library problem).

Perhaps the test given here is incorrect?

test "$oldest_abi" \< "2.2.5"

$oldest_abi is "default".

Tks,
Jeff Bailey

`They were,' said Slartibartfast.
`Yes, that's true,' admitted Arthur.
