Mark Ruvald Pedersen 86a3e8ff40 cmake: Toolchain abstraction: Introduce toolchain_ld_relocation macro
No functional change expected.

This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting non-intrusive porting to other (commercial) toolchains.

Mark Ruvald Pedersen 5f347eefe6 cmake: move configure_linker_script to ld/target.cmake
While configure_linker_script() may be useful for other linkers, it
currently only aimed at GNU ld. To really be useful among different
linkers, we would need to abstract its usage of the C preprocessor.
We can do this later, if needed.

No functional change expected.

Mark Ruvald Pedersen 65f02c04d5 cmake: Toolchain abstraction: introduce toolchain_ld_baremetal()
The intent of toolchain_ld_baremetal() is to collect the flags belonging
to non-hosted (i.e. POSIX-based) targets.

Mark Ruvald Pedersen 4080818300 cmake: Toolchain abstraction: move LINKERFLAGPREFIX under GNU ld
* LINKERFLAGPREFIX's value is GNU ld specific, and
* LINKERFLAGPREFIX is not a convention always honored by all linkers.

Thus we shall not set it from the common root CMakeList.txt.
So we move to linker/ld/target.cmake.

No functional change expected.

toolchain_ld_base() represents flags that are fundamental to linking or
otherwise does not belong in any further specified linker flag category.

Mark Ruvald Pedersen 3419efd552 cmake: fix intent description of toolchain_cc_nostdinc macro
toolchain_cc_nostdinc does not only obtain flags (to be placed in a
variable), it obtains and applies them.
