I managed to rebuild jdk14 even after "make delete-old-libs" using the
gcc34 port and bootstrapping using the Linux JDK.  I haven't yet had a
chance to see if the plugin communicates with Firefox built with the
system compiler or if there will be an ABI mismatch.

In the process I discovered two interesting quirks. The first is that
there are a number of places that set $(CXX), assuming that this is c++
compiler, and $(CPP), assuming that this is the preprocessor. This isn't
entirely true, because the hotspot build uses $(CPP) as the c++ compiler
(see hotspot/build/*/makefiles/adlc.make).  The linker bails out when it
encounters a .o file that is actually just source code that has been run
through the preprocessor. The second quirk is that overriding $(CC) in
MAKE_ARGS isn't sufficient to get the j2se portion of the build to work,
because j2se/make/common/Defs-bsd.gmk doesn't allow $(CC) to be
overridden.

I added this to MAKE_ARGS in pkgtools.conf:

        'java/jdk14' => [
            'WITH_LINUX_BOOTSTRAP=yes',
            'USE_GCC=3.4',
            'MAKE_FLAGS="CC=/usr/local/bin/gcc34 CXX=/usr/local/bin/c++34  CPP=/
usr/local/bin/c++34"',
        ],

and I had to apply this patch (to a patch):
