Disposition: submit upstream.

|

Description:
|
||||
|
||||
We do not need to have the libtool patch anymore for binutils after
|
||||
libtool has been updated upstream it include support for it. However
|
||||
for building gas natively on uclibc systems we have to link it with
|
||||
-lm so that it picks up missing symbols.
