acpid: unavailable for external uClibc toolchains

External non-patched uClibc toolchains lack the MSG_CMSG_CLOEXEC
definition, so does internal uClibc <0.9.33, so exclude it for those
scenarios. Fixes:

ne10: bump version to 1.0.0

Switch to github helper while at it.

Depend on BR2_ARM_FPU_NEON || BR2_ARM_FPU_NEON_VFPV4 so that the toolchain
wrapper will add -mfpu=neon, and avoid the following error:

.../include/arm_neon.h:32:2: error: #error You must enable NEON instructions (e.g. -mfloat-abi=softfp -mfpu=neon) to use arm_neon.h

Note that this error doesn't show in the build-end.log referenced below
because of the log lines limit.
