Ayke van Laethem a21a039ac7 arm: automatically determine stack sizes
This is a big change that will determine the stack size for many
goroutines automatically. Functions that aren't recursive and don't call
function pointers can in many cases have an automatically determined
worst case stack size. This is useful, as the stack size is usually much
lower than the previous hardcoded default of 1024 bytes: somewhere
around 200-500 bytes is common.

A side effect of this change is that the default stack sizes (including
the stack size for other architectures such as AVR) can now be changed
in the config JSON file, making it tunable per application.

Ayke van Laethem ad8996c4ee arm: fix linker script
There were a few instances like `.text` and `.text*`. The first was
redundant with the second, but the intention was to write `.text.*`.

This doesn't change anything (tested with `make smoketest`) but should
avoid propagating this error in the future.

Ayke van Laethem c6255e4d0a targets: explicitly mark the stack as NOLOAD
This prevents it from being of type PROGBITS in lld 9, it should always
be NOBITS. It should fix the following error in lld 9:

    ROM segments are non-contiguous

Ayke van Laethem 2523772b5d arm: use the lld linker
LLD version 8 has added support for armv6m:
    https://reviews.llvm.org/D55555
This means we can use LLD instead of arm-none-eabi-ld, eliminating our
dependency on GNU binutils.

There are small differences in code size, but never more than a few
bytes.

Ayke van Laethem 5b0aaf0d39 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.
