libstdc++: Replace hyphens in effective target keywords

An effective target like foo-bar-baz will match a target selector of *-*-* and cause problems in the testsuite. Several libstdc++ et keywords are of the form foo-bar, which could still be a problem for *-* selectors. Replace hyphens with underscores in the et keywords "debug-mode", "cxx11-abi", etc. libstdc++-v3/ChangeLog: * testsuite/lib/libstdc++.exp: Rename effective target keywords to avoid dashes in the name. * testsuite/*: Update effective targe keywords.
