powerpc: remove checks for binutils older than 2.25
[ Upstream commit 54a11654de163994e32b24e3aa90ef81f4a3184d ]
Commit e4412739472b ("Documentation: raise minimum supported version of
binutils to 2.25") allows us to remove the checks for old binutils.
There is no more user for ld-ifversion. Remove it as well.
