mesa: added new linux-gallium and linux-gallium-debug configs
Also, remove gallium-related things from configs/default. They're in
linux-gallium now.
So the default builds are the same as they have been for Mesa/master.
Since the gl pkg-config file doesn't convey any specifics about the
backend in use, this adds a new pkg-config file for when DRI is in use.
This can be used by the xserver build to determine if the DRI and/or
GLX extensions are appropriate.
autoconf: Attempt to figure out the PIC flags for the platform
This commit adds an autoconf macro, MESA_PIC_FLAGS, which sets the
PIC flags according to platform and static/shared setting. The platform
specifics are taken straight from libtool.m4 and stripped down to just
the flags and platforms we cover in Mesa. This should hopefully make it
possible to use autoconf on non-GCC platforms.
The macro is added external to configure.ac in acinclude.m4 since it's
pretty bloated.
Note to BSDers: Previously, x86 defaulted to non-PIC on FreeBSD. I
didn't carry that preference into this macro. Instead, you can just use
--disable-pic where desired.
Mostly some pedantic changes such that `make clean' always ignores
errors. Also changed the top clean target to do the `touch
configs/current' dance instead of realclean.
Consistently cleanup the depend.bak files created by makedepend. Also,
realclean has been changed to use a single find command, which speeds it
up considerably.
Add .PHONY targets to top Makefile for non-file targets
When a make target doesn't result in a file of the same name, adding it
to a .PHONY target means make won't look for such a file, speeding the
build up a bit. This allows `make doxygen' to work since otherwise make
will consider the doxygen directory as up to date.
