adding LDFLAGS / lts issue

[Riccardo Mottola via devel]

Hi,

I am havinng an issue while compiling gnustep-back on solaris9:

__tls_get_addr is not found (dependency from pixman)


the solution should be to add -lpthread (not needed on Solaris 10 or 
later, sicne moved inside libc)


I thought of adding


EXTRA_LDFLAGS += -lcairo
EXTRA_LDFLAGS += -lpthread


but it doesn't do anything, appears to have no effect, I check the 
config.log


Am I using the wrong variable, does it exist at all? Or maybe some other 
trick is needed to use it properly.
