net/mpich2: fix pkg-plist when JAVA option disabled, but while here...

When the default JAVA option is turned off, the check-plist fails due
to four files that don't get installed, so prefix them with %%JAVA%%

While here:
 * Fixing stage-qa with INSTALL_TARGET=install-strip
 * Manually strip JAVA option library libTraceInput.so as needed
 * Remove obsolete @dirrm
 * Add CFLAGS related to using ports execinfo to find the execinfo.h
   (ports GCC seem to look in /usr/local/include by default, but DF's
    base compiler does not, so explicitly specify this location)

All of these should be covered under the "Just Fix It" blanket
