gcc-cross: Make gcc-cross-initial as the only intermediate gcc stage
Now glibc can be compiled with gcc-cross-initial therefore prepare the stage to drop gcc-cross-intermediate Also drop arm-nolibfloat.patch should not be needed anymore half of changes in this patch are meant for OABI which we dont use anymore (From OE-Core rev: 30617bde61a3b0a0944b49a0c9fb7159dacbb19f) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

3# Dimitry Andric <dimitry@andric.com>, 2004-05-01
4#
5# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
6# anymore. (The required functions are now in libgcc.)
7#
8# Fixes errors like
9# arm-softfloat-linux-gnu/3.4.0/../../../../arm-softfloat-linux-gnu/bin/ld: cannot find -lfloat
10# collect2: ld returned 1 exit status
11# make[2]: *** [arm-softfloat-linux-gnu/gcc-3.4.0-glibc-2.3.2/build-glibc/iconvdata/ISO8859-1.so] Error 1
12# when building glibc-2.3.3 with gcc-3.4.0 for arm-softfloat
