The main problem with linking is not MAME, or the number of drivers, but the default linker being absolute awful. Even on a single driver build, from an SSD, it can take 8 minutes to link here for every minor change.
If you type
set ARCHOPTS=-fuse-ld=lld
before doing the initial 'make' that builds the scripts, then you use the alternate linker, which links, basically instantaneously.
Quite how / why the default linker is so bad I don't know.
There are downsides to this, I believe it was mentioned it doesn't work properly with the debug symbols and such (haven't tested, as I haven't needed to recently) but for day to day MAME development it's basically essential.
