[Buildroot] [git commit] erlang: Remove BR2_TOOLCHAIN_HAS_THREADS dependency

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=cbcecc2453ec7f94d82f32a1acd33a09e576ecee
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Erlang can be built without threads support, by passing an
appropriate config option.

This commit drops the config dependency on BR2_TOOLCHAIN_HAS_THREADS
and instead passes --disable-threads if the toolchain doesn't support
threads.

While here, change the wording of the config comment to "dynamic
library" to be consistent with similar comments elsewhere.
