parts of the code later on, in particular the upgrade code.
Eg: a base path of "/home/xyz/unrealircd/"
Side note: this also assumes no path is / (root), which seems a
reasonable assumption.
First, what we call local-curl is a situation where the system does not have
the cURL library installed and UnrealIRCd offers to compile and use it.
The problem is that CURLDIR in config.settings may refer to an old directory
such as /home/xyz/unrealircd-5.2.1/extras/curl and UnrealIRCd 6 would try to
use it. That would be problematic as it would result in: 1) no cURL updates
anymore since it is only half-detected as local-curl, and 2) once you remove
the unrealircd-5.2.1 directory (since you are on U6) it breaks as well.
So, we now check for this situation and in case of something that looks like
a local-curl situation, change the path to <currentunreal>/extras/curl and
download and compile cURL fresh, as expected.
All this is only for the like 1% users that uses local-curl, which then
used ./unrealircd upgrade or ./Config -quick.

1) All IRC clients support prefixes nowadays
2) People generally misunderstand the question and think this
disabled +q (channel owner) and +a (channel admin), when
in fact it does not. It only enables/disables the showing
of prefixes, and it changes some of the rules eg requiring
+qo / +ao for actions that normally only require +q / +a.
3) We now have the modularized +q and +a, so you can actually
disable channel owner and channel admin, which is what most
users want(ed) that previously disabled PREFIX_AQ.
For all users (95%+) that enable PREFIX_AQ there is no effective
change. For the other 5% it is likely only for the better.
I don't think there were more than a handful of people who disabled
this, and it clutters the source badly (not to mention that this
should not be a compile time option at all).
Also, check for GNU make (which can be either 'make' or 'gmake')
early in ./Config and print out an error to install prerequisites
from https://www.unrealircd.org/docs/Installing_from_source
This also replaces 'make' with ${MAKE} (and such) everywhere.
