Mainly so the makefile is a bit less esoteric to use, debugging flags
must be specified manually.
changed:
- `$RM` for calling `rm`
- removed unused `$ISWIN`
- renamed `test` to `check`
- added `install` and `install-strip` recipes, which for now remain
empty
- added `-g` to `$CFLAGS`, since it helps debugging, and in case of
failures makes bug report less of a headache.
I decided to not modify it further so "specialised tools" don't need to
store files in the git repo, which seemed to complicate logic.
This is the same reason to why I chose to not adapt clean in a way to
introduce `mostlyclean`.
this is a bit confusing, since setting `LD=cc` would have the same
issue; `ld: -f may not be used without -shared`. So I've got no idea
what is going wrong, I guess it's something funky.
This works, so we shall stick with this.
This slight discrepancy is a tad annoying, since it doesn't work
backwards so it uses my system's version. But we'll figure something for
that out later... probably.
This can help with a more nuanced compilation. (eg. use system libraries
rather than compile our own)
Furthermore, it decreases the needed compilation time, since we needn't
recompile the whole thing when having cleaned out our local sources.
