The reason this came up is that I was trying to work on the pkgsrc
jdk16, which is broken on DF.  The problem starts way back with the
later linux binary releases of jdk14.  Every release after that will
segfault on DF and so it's impossible to build a native jdk for DF
or even emulate one with linux.

I thought about installing some emulated linux debugging tools but
pkgsrc seems not to offer such a linux package.  ATM I'm stumped.
Any general idea how you would approach this? -- If you had the
time, of course, and I know you don't.
