[PATCH][tips] Getting PGO working with firefox 23

[Howard Goldstein]

This was a very interesting (in the sense of a curse) problem because
the moz folks have such a powerful build system that they're in the
middle of reworking.

Clang is awesome but doesn't have dynamic optimization yet, a la PGO,
and it makes a huge difference on my nancy boy Asus notepad when PGO is
not running.

To get PGO working with ff23, first apply the recent patch that gets rid
of --disable-tests in bsd.gecko.mk;   --disable-tests must not be
present or else PGO building will fail.

 While in bsd.gecko.mk because I am on STABLE-9 I also disabled the
jemalloc enable and all of the jemalloc config defs.  (nb., thunderbird
wont build with gcc47 or 48 if jemalloc is enabled even if PGO is off)

At this point you should have --disable-tests gone and maybe jemalloc.
The shar that follows include the two patches to get past the compile
failure at the gmake -C ipc export   phase (this failure states that
target "app/Makefile" doesn't exist.
