produced packages are named according to PKGNAME-main/PKGNAME-wx) but
means that the port work directory has 'erlang' in the name rather
than 'otp', making it easier to identify the responsible port when
searching a big tree of source unpacked with "make extract".
- pick some <space><tab> nits while there
from configure and disable explicitly it on arm and hppa. The 4
versions build fine on amd64 with and without smp enabled. The port
will also add a symlink to the erlang interpreter on those
architectures to avoid the use of a PFRAG file.
