This is a regression of a problem we had before. The problem is reintroduced by
the 'fix' to a comment a couple of posts above, about removing the specification
of CFLAGS and CXXFLAGS for the 'install' pass. By removing those, the command
line to the compiler changes, which SCons sees as a dependency change, so
rebuilds all files with the new command line. The only way round this is to
leave the CFLAGS and CXXFLAGS declarations in the 'install' pass so that the
settings seen by SCons are identical to those used during the 'build' pass.
