Ignore errors due to strict-overflow warnings; strip clang-only flag on non-clang builds. Concerning the latter "fix", it's not entirely clear to me why the -Wno-format-pedantic flag ends up being passed to gcc, the .gyp file appears to already condition the inclusion of this flag on whether cc=clang.
