[PATCH] ld-plugin/lto.exp: Disable tests with gcc older than 4.7.0.

[Will Newton]

The test for ld/12942 fails with gcc versions before 4.7.0. This patch
disables running the LTO tests with these versions of gcc. Disabling
the test in a more fine-grained way would be a bit more complex and it
appears that binutils developers are all using newer gccs anyway.
