I've been building modular for about a year now using a bunch of custom
wrappers around build.sh I wrote to allow using a DESTDIR and not installing
on the build machines.

I have a single checkout of cvs/git sources and use lndir to make links to
it from directories in which I build 32-bit & 64-bit on both SPARC & x86/x64
for Solaris, and even gcc vs. Sun compilers.

I also use a install.sh hacked to skip the install of any file name ending
in .la.

They do things like this:

MYTOPDIR=/export/sata/alanc/X.org/mod
MYARCHDIR=`pwd | sed 's%^.*/export/sata/alanc/X.org/mod/\([a-z0-9\-]*\).*$%\1%'`
MYUTILSDIR=${MYTOPDIR}/myutils

PREFIX=/usr/X11R6
DESTDIR=${MYTOPDIR}/${MYARCHDIR}/install
INSTDIR=${DESTDIR}${PREFIX}

export DESTDIR

case $MYARCHDIR in
     *-gcc)
         CC="gcc" CXX="g++" F77="g77" CFLAGS_64="-m64"
         GENERIC_CFLAGS="-O2 -Wall"
         ;;

         GENERIC_CFLAGS="-v -xO4 -xbuiltin=%all -xlibmil -xstrconst -xildoff"
         ;;
esac


if [ x$DEBUG = x1 ] ; then
     GENERIC_CFLAGS="-g -v"
