This is a minimal set of changes to allow `serenity.sh build riscv64` to successfully generate the build environment and start building. This includes some, but not all, assembly stubs that will be needed later on; they are currently empty.

# FIXME: We could eliminate this setting by building LibC and support asm files (crti.o, crtn.o)
|
|
# in a separate build stage before the main build to ensure that LibC is available
|
|
# for the try_compile check for the main build.

# Note that `set(CMAKE_TRY_COMPILE_TARGET_TYPE STATIC_LIBRARY)` is not a suitable replacement,
|
|
# since applications might try and use `try_compile()` to detect which library a symbol is in,
|
|
# which doesn't work when using static linking.
|
|
# Instead, just tell CMake directly that the compiler works fine, so that it doesn't have to run
|
|
# a compile check before the build.
