Thomas Petazzoni 8cba5463de support/scripts/gen-bootlin-toolchains: do not assume RPC for glibc toolchains 
The logic in gen-bootlin-toolchains was assuming all glibc toolchains
have RPC support, which is no longer true since glibc 2.32 has dropped
RPC support.

It turns out that gen-bootlin-toolchains already had some proper logic
that selects BR2_TOOLCHAIN_HAS_NATIVE_RPC depending on the presence of
BR2_TOOLCHAIN_EXTERNAL_INET_RPC in the toolchain fragment. As such
toolchain fragments have been fixed in https://toolchains.bootlin.com,
we can now rely on this to properly decide if the toolchain has RPC
support or not.

# In the below dict:
# - 'conditions' indicate the cumulative conditions under which the
# toolchain will be made available. In several situations, a given
# toolchain is usable on several architectures variants (for
# example, an ARMv6 toolchain can be used on ARMv7)
# - 'test_options' indicate one specific configuration where the
# toolchain can be used. It is used to create the runtime test
# cases. If 'test_options' does not exist, the code assumes it can
# be made equal to 'conditions'
# - 'prefix' is the prefix of the cross-compilation toolchain tools
