[rabbitmq-discuss] Building RabbitMQ-server with make 3.80

[Matthew Sackman]

Hi,

Recently several people have reported issues with building the broker
with make 3.80. This seemed to affect at least people with some versions
of OS X / xcode as well as older RHEL/Centos releases.

This has now been fixed : the head of the default branch of
rabbitmq-server now builds correctly with versions of make as old as
3.80.

It turned out to be due to depending on a variable .DEFAULT_GOAL which
was only introduced in 3.81. We've worked around that problem, and also
have a meaningful explosion if anyone tries to compile with a version of
make older than 3.80.

Needless to say, this will appear in the next release.
