package/glibc: disable on RISC-V ilp32f and lp64f, not supported

Browse Source 
glibc fails to build on RISC-V 32-bit with the ilp32f ABI and on
RISC-V 64-bit with the lp64f: both use single-point precision floating
point, which glibc doesn't support, failing during the configure step
with:

  configure: error: glibc does not yet support the single floating-point ABI

Fix that by disabling glibc support on those configurations.
