gcc-3.4.0-arm-nolibfloat.patch

linux下编译交叉工具链的工具源码

# Dimitry Andric <[e-mail]>, 2004-05-01
#
# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
#   anymore.  (The required functions are now in libgcc.)
# 
# Fixes errors like
# arm-softfloat-linux-gnu/3.4.0/../../../../arm-softfloat-linux-gnu/bin/ld: cannot find -lfloat
# collect2: ld returned 1 exit status
# make[2]: *** [arm-softfloat-linux-gnu/gcc-3.4.0-glibc-2.3.2/build-glibc/iconvdata/ISO8859-1.so] Error 1
# when building glibc-2.3.3 with gcc-3.4.0 for arm-softfloat
