Existing logic in autotools_preconfigure() will clean the build directory
before rerunning configure in the case where ${S} != ${B}. It is, however,
desirable to make at least some attempt to clean the build artifacts for
in-tree builds since many packages lack the appropriate dependency rules
to force a recompile if (for example) CFLAGS has changed. Making distclean
would be better but is not practical because many packages don't support it
properly. Even "make clean" is not universally available, so we ignore any
failure from that command and just carry on regardless.
