[Buildroot] [git commit] package/uclibc: prevent config with unsupported RISC-V float ABI

[Thomas Petazzoni via buildroot]

commit: https://git.buildroot.net/buildroot/commit/?id=9a51381cedc16e6d70cb85e1144f6e0fa89af69a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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:

[Thomas: instead of !BR2_RISCV_ABI_LP64F, use BR2_RISCV_ABI_LP64 ||
BR2_RISCV_ABI_LP64D]
