ARM 용 툴체인 설치 관련 질문 드립니다.

arm용으로 설치 중인데 왜이런지 조언 구합니다.
질문 내용이 좀 길어도 이해 해주시고 한번씩 봐주세요.

tar -jxvf linux-2.6.23.8.tar.bz2
cd linux-2.6.23.8
gzip ../patch-2.6.23.8-my.gz | patch -p1
make xconfig

cd cross4.1
tar -jxvf gdb-6.4.tar.bz2
cd gdb-6.4
mkdir build
cd build
../configure --target=arm-linux --build=i686-pc-linux-gnu --prefix=/usr
make
make install

tar -jxvf binutil-2.16.1.tar.bz2
cd binutils-2.16.1

==> gcc 컴파일 하기전
vi gcc/config/arm/t-linux
TARGET_LIBGCC2_CFLAGS = -fomit-frame-pointer -fPIC -Dinhibit_libc -D__gthr_posix_h

LIB1ASMFUNCS = _udivsi3 _divsi3 _umodsi3 _modsi3 _dvmd_lnx \
_negdf2 _addsubdf3 _muldivdf3 _cmpdf2 _unorddf2 _fixdfsi _fixunsdfsi \
_truncdfsf2 _negsf2 _addsubsf3 _muldivsf3 _cmpsf2 _unordsf2 \
_fixsfsi _fixunssfsi
요렇게 수정하고.
vi gcc/config/arm/linux-elf.h
#define LIBGCC_SPEC "%{msoft-float:-lfloat} %{mfloat-abi=soft*:-lfloat} -lgcc"
==>#define LIBGCC_SPEC "-lgcc"
어렇게 수정 마무리 했습니다.

tar -jxvf gcc-4.1.0.tar.bz2
cd gcc-4.1.0
mkdir build
cd build

긴 질문을 봐주셔서 정말 감사합니다.
앞으로 삽질할것도 많은데 여기서 막혀서 헤매고 있네요..
/usr/include 에 파일은 있는데 왜 못찾고 있는지..
혹 다른 문제 때문에 발생하는건지 감을 못잡고 있습니다
그럼 오늘 하루도 다들 수고하세요.
