Go testsuite patch committed: Add -I. when compiling in directory

[Ian Lance Taylor via Gcc-patches]

This Go testsuite patch adds a -I. argument when compiling sources in
a directory.  This tells the compiler to import packages in the
current directory first, which is what we want in the testsuite.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.

* go.test/go-test.exp (go-gc-tests): Add -I. when building all
sources in a directory (errorcheckdir, compiledir, rundir,
rundircmpout).
