klibc only has a riscv64 port, which hardcodes KLIBCBITSIZE = 64 and
uses 64-bit loads and stores in its assembly, and upstream has no
riscv32 port. With KLIBC_ARCH defaulting to TARGET_ARCH, the build fails:

  make[1]: *** No rule to make target '.../usr/klibc/arch/riscv32/MCONFIG'.  Stop.

Mark klibc and the recipes sharing klibc.inc incompatible with riscv32
so they are skipped instead of failing to build.

Also skip all recipes inheriting klibc
