a0690b69da math: add functions; update tests and special cases
Added special cases to comments for asin.go and fabs.go.
Added Trunc() to floor.go and floor_386.s.  Fixed formatting
error in hypot_386.s  Added new functions Acosh, Asinh,
Atanh, Copysign, Erf, Erfc, Expm1, and Log1p.  Added
386 FPU version of Fmod.  Added tests, benchmarks, and
precision to expected results in all_test.go.  Edited
makefile so it all compiles.

d4ca006334 math: 386 FPU hypot
Added 386 FPU version of Hypot; modified all_test.go to test
Hypot with large arguments.  Also edited sqrt.go to remove
Sqrt(0) as a special case.

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.

488ca3c7a6 move math out of runtime.
a step toward enforcing package boundaries,
necessary to eliminate global package name space.

3b864e4195 convert low-level (used by testing) packages to
whole-package compilation.  new Makefiles,
tests now in separate package

	bytes
	flag
	fmt
	io
	math
	once
	os
	reflect
	strconv
	sync
	time
	utf8

delete import "xxx" in package xxx.

inside package xxx, xxx is not declared
anymore so s/xxx.//g

delete file and package level forward declarations.

note the new internal_test.go and sync
and strconv to provide public access to
internals during testing.  the installed version
of the package omits that file and thus does
not open the internals to all clients.
