40ff071e9b 5g/8g, 8l, ld, prof: fix output of 32-bit values
If an %lld argument can be 32 or 64 bits wide, cast to vlong.
If always 32 bits, drop the ll.
Fixes #1336.

c72fb37425 prof: install gopprof too
This is a modified version of the open source pprof
from code.google.com/p/google-perftools.
That version is likely to catch up to this one,
but it's still useful to ship our own copy since
we only need the one script from that project,
not all the C++ libraries.

8c557962de make 6prof (sic) architecture-independent.
for now, it's amd64 and 386 only but it's trivial to add more.

Fixes #385.

(why couldn't it have been issue 386?)

tested for amd64 and 386 on darwin.

6fc820729e go: makes it build for the case $GOROOT has whitespaces
the bash scripts and makefiles for building go didn't take into account
the fact $GOROOT / $GOBIN could both be directories containing whitespaces,
and was not possible to build it in such a situation.

this commit adjusts the various makefiles/scripts to make it aware of that
possibility, and now it builds successfully when using a path with whitespaces
as well.

Fixes #115.

0489a260da FreeBSD-specific porting work.
cgo/libmach remain unimplemented. However, compilers, runtime,
and packages are 100%. I still need to go through and implement
missing syscalls (at least make sure they're all listed), but
for all shipped functionality, this is done. Ship! ;)

586d9d5a19 use $(shell uname) instead of $GOOS when
deciding what the host process support is.
this makes a cross-compiling (e.g., GOOS=nacl) build
still generate valid host debugger binaries.

736903c170 libmach:
* heuristic to go farther during stack traces.
	* significantly improved Linux thread handing.

acid:
	* update to new libmach interface.

prof:
	* use new libmach interface.
	* multiple thread support (derived from Rob's copy).
	* first steps toward pprof-like graphs:
	  keep counters indexed by pc,callerpc pairs.
