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.
Because of this bug, filtering of exported symbols was not taking
place with crosstool-NG toolchains.
This issue has bee noticed when building pango, which exported
harfbuzz symbols that should have remained hidden.
