See the output of
./configure --help
Commonly, I find it sufficient to specify the alternate location via:
./configure --prefix=/path/where/pg/stuff/should/live
That implies bin/, include/, share/, lib/ and other such target
directories. If you have very specific needs, configure options should
hopefully accommodate them.

That's not a standard place to put #include files across all of the
operating systems on which Postgres runs, so it wouldn't be proper to
have it as a default.
Not all systems have /usr/local/include, and on some systems, adding
this would point the compile to *wrong* code. Consider the case where
an engineer at a company like Red Hat (Tom? ;-)) is building official
packages for a Linux distribution.
- On the machine where the build is being done, there might well exist a
/usr/local/include directory.
- But it shouldn't be used, because the *right* #includes to use for the
build are in /usr/include.
- They might have /usr/local/include there specifically as a test that
programs should *NOT* be referencing it without specific instruction
to do so! I could imagine stowing #includes there that are designed
to make stuff break. Probably not a good thing on an Official Build
Server, but an excellent torture test for a QA server :-).
