Of Course. Use --prefix= and omit the other options which integrate it
with the Ubuntu-specific install locations.

Alternatively
--program-suffix= can be used to append a specific value to the end of
all the installed binaries. The configuration files and helpers all have
config directives to alter them, and will default to the suffix'ed
version of each file.
