From: Lennert Buytenhek <buytenh@wantstofly.org>
Hi,
The reason that building nss (i.e., firefox) would segfault on ARM EABI
systems is an assumption about the layout of the jmp_buf structure in
the nspr library (which nss depends on) that does hold on old-ABI but
no longer holds on EABI. The attached patch fixes this assumption,
and fixes the shlibsign segfault during the building of nss (it also
fixes a floating point byte order assumption.)
Looks sane?
It's of course a stupid idea to depend on a particular layout of the
jmp_buf structure in application programs, but oh well. People write
ugly buggy code, film at 11.
