#46331: libtool contains references to ccache when it was built with ccache
--------------------------+----------------------

     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.3.3
 Keywords:                |       Port:  libtool
--------------------------+----------------------
 If my MacPorts installation is configured to use ccache at the time that
 the libtool port is built and installed, then the installed copy of
 libtool contains references to ccache and uses ccache when other software
 uses libtool, even if those other ports have requested that ccache be
 disabled.

 {{{
 $ grep ccache /opt/local/bin/glibtool
 LTCC="ccache /usr/bin/clang"
 CC="ccache /usr/bin/clang"
 CC="ccache /usr/bin/clang++"
 }}}

 In fact it looks like it contains references to the compiler (clang in
 this case) as well.
