Well, we don't, with a normal not-PG-specific install path.
What I get with --prefix=/home/tgl/testversion is
$ ls ~/testversion/lib

libecpg.so.6.4* libpgport.a libpq.a
libecpg_compat.a libpgtypes.a libpq.so@

which seems perfectly sane from here. The issue is that if the
install directory path already has "postgres" somewhere in it,
you get a different layout where the PG-specific subdir is smashed
together with the user libraries.
I tend to agree with the OP that that case isn't great, but we've
had it like this for so long that I'm not sure we can change it.
OTOH, the issue probably only affects PG developers, so maybe
we could?

Yeah, you'd have to resort to editing Makefile.global after
configuring, which is annoying.
