[U-Boot] [PATCH v2] Make linking against libgcc configurable

[Daniel Gorsulowski <Daniel.Gorsulowski@esd.eu>]

Hello Heiko,

Dirks patch reduces the errors, but I still get:

drivers/mtd/nand/libnand.a(nand_base.o): In function `nand_do_write_oob':
/data/home/danielg/git/u-boot/drivers/mtd/nand/nand_base.c:2019: undefined reference to `__lshrdi3'

make: *** [u-boot] Error 1

I noticed, that lib_arm/_lshrdi3.a is not beeing compiled.
So i added 'GLSOBJS += _lshrdi3.S' to lib_arm/Makefile (this line is missing
in your patch, i guess). But _lshrdi3.a still does not compile.

So I took a look at lib_arm/.depend:
_ashldi3.o: _ashldi3.S
_ashrdi3.o: _ashrdi3.S
_divsi3.o: _divsi3.S
_lshrdi3.o: _lshrdi3.S
_modsi3.o: _modsi3.S
_udivsi3.o: _udivsi3.S
_umodsi3.o: _umodsi3.S

I have no explanation for that, do you have?

bye, Daniel
