In fact, now that I think of it, why don't we use the mysql_config
script here ?

I.E:

OPEN2300_CFLAGS += $(shell $(STAGING_DIR)/usr/bin/mysql_config --cflags)
OPEN2300_LDFLAGS += $(shell $(STAGING_DIR)/usr/bin/mysql_config --libs)

this way the static linking mess can be hidden inside the mysql_config
script, and hopefully factored out from all the packages using mysql.

What do you think ?
