[Buildroot] [PATCH v2 1/1] ltp-testsuite: support building with toolchains without native RPC

[Thomas De Schampheleire]

From: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com>

ltp-testsuite needs RPC, but this could also be provided by libtirpc.

The dependency of libtirpc on
!BR2_TOOLCHAIN_EXTERNAL_BLACKFIN_UCLINUX_2012R2 does not need to be
propagated, because it is always satisfied: ltp-testsuite depends on
BR2_USE_MMU which is always unset for Blackfin targets.

Since musl toolchains never have RPC support, this change would now allow
building of ltp-testsuite on musl toolchains. Unfortunately, ltp-testsuite
does not build yet with musl, so a specific check on musl is added.
This is deemed more conceptually correct than checking on glibc||uclibc.

v2:
- clarify dependency propagation for blackfin in commit msg (Yann)
- clarify intentional wording of non-musl.
- use pkg-config instead of fixed C/LDFLAGS (Yann)
