linking process. This is needed because we change the source object
files and the second this dtrace -G is run, no probes will be found.
This hack allows us to build postgres with DTrace probes enabled. I'll
try to find a way to fix this without needing this hack.

Summary of changes:
* Implement a compatibility shim between Solaris libproc and our
libproc and remove several ifdefs because of this.
* Port the drti to FreeBSD.
* Implement the missing DOODAD sections
* Link with libproc and librtld_db
* Support for ustack, jstack and uregs (by sson@)
* Misc bugfixing
When writing the SUWN_dof section, we had to resort to building the ELF
file layout by "hand". This is the job of libelf, but our libelf doesn't
support this yet. When libelf is fixed, we can remove the code under
#ifdef BROKEN_LIBELF.

'lib32' for 32-bit binaries on amd64 and 'lib' for 64-bit binaries.
Remove an #ifdef __i386__ that defined use32 to the wrong value on
i386 to workaround the bug in the terenary operator.
