This has been asked twice in the past week, so I will post a response.

Page 268 of "Using and porting Gnu CC" version 2.3 (16 Dec 1992)
says that the order of prefixes tried for the executable files (as, ld, cc1, etc.)
is

1. Any prefix es specified by the iuser with -B

2. The environment variable GCC_EXEC_PREFIX, if any

3. The directories specified by the environment variable COMPILER_PATH

4. The macro STANDARD_EXEC_PREFIX (which should be defined in 
	machine.h for your particular machine.)

5. /usr/gnu/lib/gcc-lib/<machine>/<version>

6. The macro MD_EXEC_PREFIX

So, if you want a specific linker, assembler, preprocessor, whatever,
only a few times, but you normally want the system programs for that
job, then just use -B to tell gcc where they live.  They must
haveee the statndard names:

preprocessor : cpp
compiler : cc1
assembler : as
linker : ld

Otherwise, if you wantto always have a "customized" setup, then put links 
with those names in /usr/lib/gcc to whatever programs you want to have those
duties.
