The macro $(SYSTEM_HEADER_DIR) is used in a double-quoted context,
leading to nonportable "...`..."..."...`...",  see
<http://www.gnu.org/software/autoconf/manual/html_node/Shell-Substitutions.html>.

Proposed untested patch.  (I also haven't checked whether there are
other instances of this issue in 'make install' code.)

Cheers,
Ralf
