- The compile option variable has to be defined as list.
- The compiler works in relaxed ANSI mode by default.
Strict ANSI has to be explicitly set additionally to the
language standard.
If e.g. libc.a is passed before any objects the linker raises the follwing
warning: cannot resolve archive libc.a to a compatible library, as no
input files have been encountered
In the end the library is skipped and missing symbols occur.

Teach the Makefile and Ninja generators to substitute for an <INCLUDES>
placeholder instead of putting -I in <FLAGS>. Update our values for
CMAKE_<LANG>_COMPILE_OBJECT,
CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and
CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE
to place <INCLUDES> just before <FLAGS>.
