question about hppa - parisc support

[Waldemar Brodkorb <wbx at openadk dot org>]

Hi libc hackers,

is there any special thing todo, to build a parisc toolchain?
Tried Linux 3.19, gcc 4.9.2 and binutils 2.25, but it fails with glibc
2.20/2.21/git.

Error for 2.21:

Anything I can do?
The error for git is another one.

The README says, not possible without patches, but where can I find
these patches?

best regards
