crosscompile, libtools aund buildtools

[Benedikt Spranger]

Hi,
During crosscompile I often have a problem: I need some to build
build-tools like rpcgen. How can I do it the right way? 
Until now I use the following code:
configure.in:
----8<----
if test -z "$CC_FOR_BUILD"; then
# to avoid recursive substitution
#       if test "x$cross_compiling" = "xno"; then
#               CC_FOR_BUILD='$(CC)'
#       else
                CC_FOR_BUILD=gcc
#       fi
fi
----8<----
Makefile.am:
----8<----
CC=$(CC_FOR_BUILD)
CFLAGS=$(CFLAGS_FOR_BUILD)
LDFLAGS=$(LDFLAGS_FOR_BUILD)
LIBTOOL = @LIBTOOL@ --tag=CC
----8<----
Is there a better way to do it?
