libgo patch committed: Skip type descriptors in testsuite script

[Ian Lance Taylor]

This libgo patch changes the testsuite script to explicitly skip type
descriptors.  Type descriptors are normally weak and GNU nm will
report them as V, so we will skip them when collecting the list of
symbols.  But when not using GNU nm, they may be reported as D, so
also skip them in symstogo.  This fixes go/doc/check on Solaris.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.
