I don't see how you're still getting the -Wl,-Bstatic flag with the
above CONFIG_SITE file, unless something else is overriding the setting
STATIC_BUILD=NO such as your application's own configure/CONFIG_SITE file.

Mark's suggestion that you should use PROD_SYS_LIBS instead of PROD_LIBS
to link this vendor library is correct and may help, but doesn't explain
the above issue.
