ld from crosstool-NG reports a version string with an extra version:
GNU ld (crosstool-NG 1.13.0) 2.21.1

This made libtool assume that the ld version was the crosstool-NG
version (1.13.0) instead of the real ld version (2.21.1).

To fix the ld version string, this patch filters out any string
between parentheses that is followed by a space.

Committed. Thanks! (I suspect we were also running into this; our internalbuilds of ld and gold also have version numbers embedded in theparenthetical note.)

If you could give the updated libtool.m4 file a test to make sure it'sworking as expected, I'd appreciate it.
