package/uclibc: prevent config with unsupported RISC-V float ABI

Browse Source 
uClibc currently supports RISC-V with a soft-float or 64-bit
hard-float ABI, but not 32-bit hard-float. Selecting
BR2_RISCV_ABI_LP64F results in a build failure:

./include/sys/asm.h:42:4: error: #error unsupported FLEN
   42 | #  error unsupported FLEN
      |    ^~~~~

Change the conditions for BR2_PACKAGE_UCLIBC_ARCH_SUPPORTS
accordingly.

Fixes:

BR2_RISCV_ABI_LP64D]
