build: work around ICC's limitations

Browse Source 
Several types of failures.  First, unable to pass the file name
properly to the linker.

    ./synclines.at:416: $CC $CFLAGS $CPPFLAGS  $LDFLAGS -o \"\\\"\" \"\\\"\".c $LIBS
    stderr:
    ld: cannot open output file "/"": No such file or directory
    stdout:

Unable to save under such a file name.

    ./synclines.at:421: $CXX $CXXFLAGS $CPPFLAGS -c $LDFLAGS -o \"\\\"\" \"\\\"\".cc $LIBS
    stderr:
    error: can't open file "/"" for write
    compilation aborted for "\"".cc (code 1)

Spurious output because of warning flags is failed to reject as an
error during configure:

    ./headers.at:343: $CXX $CXXFLAGS $CPPFLAGS $LDFLAGS c-only.o cxx-only.o -o c-and-cxx ||
              exit 77
