[U-Boot] problem building next on P2020DS_36BIT

[Kumar Gala]

I'm seeing the following build compile error related to building the next tree on P2020DS_36BIT.  What's odd is that git bisect says its related to:

commit 4b142febff71eabdb7ddbb125c7b583b24ddc434
Author: Heiko Schocher <hs@denx.de>
Date:   Thu Dec 3 11:21:21 2009 +0100

    common: delete CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL

...

But that seems very odd to me.  The other thing is if I run 'make' again it completes.

Scott,

This appears to be related to .depend generation and the patch that seems to cause the issue is:

Author: Scott Wood <scottwood@freescale.com>
Date:   Wed Nov 4 18:41:41 2009 -0600

    makefiles: fixes for building build tools
    
    Currently, some of the tools instead set CC to be HOSTCC in order to re-use
    some pattern rules -- but this fails when the user overrides CC on the make
    command line.  Also, the HOSTCFLAGS in tools/Makefile are currently not
    being used because config.mk overwrites them.

It looks like for some reason we aren't getting the EXTRA_CFLAGS in drivers/bios_emulator/Makefile aren't getting picked up in the .depend generation.

EXTRA_CFLAGS is not part of the u-boot build system.  CFLAGS is, but it 
is not used in dependency generation.

Prior to that change, HOSTCFLAGS was being used inappropriately in 
generating target dependencies.  If you change the HOSTCFLAGS reference 
in drivers/bios_emulator/Makefile to CPPFLAGS, it works.

Unfortunately, that makefile still has to update CFLAGS as well, because 
it's too late at that point for changes to CPPFLAGS to propagate to CFLAGS.
