    Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in toolchain files · a66004be

    Document these variables.
    Change our convention for setting these variables from:
        set(CMAKE_C_FLAGS_INIT "...")
        string(APPEND CMAKE_C_FLAGS_INIT " ...")
    so that any value previously set by a toolchain file will be used.
    Automate the conversion with:
        sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \
          Modules/Compiler/*.cmake Modules/Platform/*.cmake
    and follow up with some manual fixes (e.g. to cases that already
    meant to append).  Also revert the automated changes to contexts
    that are not protected from running multiple times.
