Subject: toolchain: introduce HOSTCC_VERSION and fix gcc-4.3.x build with old
 host CCs

gcc < 4.2.0 doesn't support -Wno-overlength-stings, but gcc-4.3.x configure
fails to detect that, breaking the build.

Work around it by detecting the host gcc version (and store in HOSTCC_VERSION)
and set the proper configure variables for gcc < 4.2.0.
