Florian Fleissner 6334f327fb Fixed build errors with follow up builds after a failed attempt to link 
In rare occasions during development when e.g. a missing symbol caused
the linker process to abort, the joined library was not removed
at the end of the build. In subsequent builds this possibly
caused problems during creation of the joined library as a
static library cannot be updated but must be removed and re-created.

This change solves the described problem by removing a possibly
pre-exising joined library before the link.

## PLEASE NOTE: The way we link our elf binary significantly differs from the
## way that Arduino handles things by default.
## The original linker command has been split up into three
## steps (recipe.c.combine.pattern, recipe.hooks.linking.postlink.1.pattern
## and recipe.hooks.linking.postlink.2.pattern).
## This is necessary to prevent link errors reporting unresolved symbols
## due to order dependencies of libraries and objects appearing
## in the linker command line.
##
## CHANGED WRT DEFAULT: Remove a pre-existing joined library. This is necessary if the library was not
## removed at the end of a previous build, because the build process
## terminated early after a failed attempt to link (e.g. because of missing symbols).
