Even though that seems weird, the LP64F ABI is only supported when MMU
support is enabled. Indeed, as per commit
9a51381ced ("package/uclibc: prevent
config with unsupported RISC-V float ABI"), uClibc does not support
LP64F. But uClibc is the only C library that support RISC-V 64-bit
noMMU.
So the selection of LP64F and !MMU is impossible. Right now this
selection causes a build failure as no C library is enabled.
This commit fixes this by ensuring we cannot use LP64F when MMU
support is not available.
