crosstool-ng/patches/glibc/2.2.2/glibc-2.2.2-allow-gcc3-dl-machine-i386.patch
Yann E. MORIN" 1906cf93f8 Add the full crosstool-NG sources to the new repository of its own. 
You might just say: 'Yeah! crosstool-NG's got its own repo!".
Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup.
That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(

Updated to repair breakage caused by unconditionally requiring ARCH_FIXUP_ATTRIBUTE
to be defined. (No wonder glibc-2.2.2 didn't build for anything but x86...)
