i want to compile bootloader for my board(adm5120). i use buildroot to build a cross-toolchain. (some tools is: binutils-2.16.91.0.2.tar.bz2 gcc-3.4.4.tar.bz2 uClibc-0.9.27.tar.bz2...), and i can use the cross-toolchain to compile my kernel, and is ok! so, i use it to compile the u-boot(the patch for adm5120 [http://www.nerdclub.nl/u-boot/adm5120-support.txt] is ok), but i got some error: . . . /root/adm5120/buildroot/build_mipsel/staging_dir/bin/mipsel-linux-ld: common/libcommon.a(memsize.o): compiled for a big endian system and target is little endian /root/adm5120/buildroot/build_mipsel/staging_dir/bin/mipsel-linux-ld: common/libcommon.a(memsize.o): endianness incompatible with that of the selected emulation /root/adm5120/buildroot/build_mipsel/staging_dir/bin/mipsel-linux-ld: failed to merge target specific data of file common/libcommon.a(memsize.o) cpu/mips/start.o: In function `reset': start.S:(.text+0x42c): undefined reference to `_GLOBAL_OFFSET_TABLE_'

anybody can tell me , where is wrong?
