toolchain's output depends on toolchain used to build the compiler?

[Omer Zak]

I suggested before to check the compiler and linker flags which are
actually used.

Now I decided to check how to actually make the checks.

According to man gcc:
-v (verbose mode) reports the final form of the include path.
--help -v reports extra information which can be helpful.

I found that for example:
gcc --help -v 2>&1 | less

when run under Linux (Debian Lenny), displays - among lots of other
information - the flags passed
to /usr/lib/gcc/i486-linux-gnu/4.3.2/collect2 (my gcc version is 4.3.2).

DISCLAIMER:
I did not check the above when invoked by makefiles with custom
compile-time flags.  Therefore, YMMV.
