targets: clean up and unify linker scripts
...
Especially arm.ld needed some cleaning up. Other than that, I've made
sure the two linker scripts look similar where possible.

This fixes a problem on baremetal targets, where PIE doesn't make any
sense. Specifically, on ARM, the compiler sometimes inserted GOT
pointers for linker-defined globals.

Force-pushing seemed like a bad idea so here it is.

compiler: add -size flag to replace size utility
...
The size flag has two modes:
-size=short: prints data basically equivalent to the `size` program.
-size=full: tries to determine sizes per package (not entirely
accurate).

avr: convert initialization from asm to Go
...
This increases code size by 1 instruction (2 bytes) because LLVM isn't
yet smart enough to recognize that it doesn't need to clear a register
to use 0: it can just use r1 which is always 0 according to the
convention. It makes initialization a lot easier to read, however.

avr: link with the GCC runtime library
...
This allows the use of some compiler-generated builtins that are
hopefully compatible with LLVM. Example: println(uint8(foo))
Code size is unchanged normally but of course compiler builtins will
increase code size when actually used (for example with division).

The sync package is strongly tied to the runtime, so it's easier to
implement a new one. Besides, it's pretty big so it's better to replace

all: rewrite sleep function
...
time.Sleep now compiles on all systems, so lets use that.
Additionally, do a few improvements in time unit handling for the
scheduler. This should lead to somewhat longer sleep durations without
wrapping (on some platforms).
Some examples got smaller, some got bigger. In particular, code using
the scheduler got bigger and the blinky1 example got smaller (especially
on Arduino: 380 -> 314 bytes).
