I don't know if anyone has a makefile for it, but the following seems to work
for me:

pgsql/src/backend$ cc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Winline -Wdeclaration-after-statement
-Wendif-labels-fno-strict-aliasing -g -L../../src/port  -Wl,-rpath,'/home/peter/devel/pg83/pg-install/lib' -Wl,-E
$(find-name "*.o" | grep -v SUBSYS | grep -v conversion_procs) ../../src/timezone/SUBSYS.o
../../src/port/libpgport_srv.a-lxslt -lxml2 -lpam -lssl -lcrypto -lgssapi_krb5 -lcrypt -ldl -lm -lldap -o postgres
 

If you find that the optimizations you are hoping for are useful, I'm sure
we could put an option of that sort somewhere in the makefiles.
