Fine.

Yep, cf. below.

Do *not* set CC when building RTEMS. 

Adding /usr/local/bin to $PATH should be sufficient. Also make sure
that cc rsp. gcc is a native c-compiler (/usr/local/i386-rtems/bin
must *not* be in $PATH).

> # export MAKE=gmake
This should not be required. Invoking gmake as "gmake" should be
sufficient in case "make" isn't "gnu-make" on your host.

This is OK.

The wrong CC is being picked up.

BTW: I do *not* recommend to use --prefix=/usr/local for building
the gnu-tools. /usr/local/include and /usr/local/lib are special
directories. Therefore installing files to these directories can
have unwanted side-effects and corrupt your system.
