This:
1) Defines the ABI hash of a package (as the SHA1 of the __.PKGDEF)
2) Defines the ABI hash of a shared library (sort the packages by import
path, concatenate the hashes of the packages and SHA1 that)
3) When building a shared library, compute the above value and define a
global symbol that points to a go string that has the hash as its value.
4) When linking against a shared library, read the abi hash from the
library and put both the value seen at link time and a reference
to the global symbol into the moduledata.
5) During runtime initialization, check that the hash seen at link time
still matches the hash the global symbol points to.

addmoduledata is called from a .init_array function and need to follow the
platform ABI. It contains accesses to global data which are rewritten to use
R15 by the assembler, and as R15 is callee-save we need to save it.

This changes the action graph when shared libraries are involved to always have
an action for the shared library (which does nothing when the shared library
is up to date).

Just a first basic test, I'll extend this to test more but want to get an
opinion on basic approach first.
