Comment (by Steven Watanabe):

 The reason this happens is:
 - clang imports gcc
 - gcc.jam calls feature.extend toolset : gcc ; at the top level.
 - build-system.jam attempts to autoconfigure toolsets based on
   whether the feature value is known.  Therefore, a plain toolset=gcc
   will not trigger autoconfiguration if clang has been used.

 Workarounds:
 - toolset=gcc-7.2.1 (or whatever the full version of gcc is)
 - add using gcc to user-config.jam.
