it is relatively simple
the book has this comment :
"Apply a patch that will allow the building of the libiberty and zlib
target libraries to be disabled as these do not build correctly in a
cross-compiled environment:
patch -Np1 -i ../gcc-4.6.1-cross_compile-1.patch"
The patch is called gcc-4.6.1-cross_compile-1.patch
NOT mpfr-<version>-cross_compile-1.patch
NOT gmp-<version>-cross_compile-1.patch
NOT mpc-<version>-cross_compile-1.patch
IF the patch was to be applied to a subdir then you would have been
told to first change to that dir, you were not , so don't
if you want to over think it, then see the above book comment again
"Apply a patch that will allow the building of the libiberty and
zlib target libraries to be disabled "
Prepare GCC for compilation:
../gcc-4.6.2/configure \
<snip>
--disable-target-libiberty --disable-target-zlib \
<snip>
notice that ../gcc-4.6.2/configure is not ../gcc-4.6.2/gmp/configure
OR ../gcc-4.6.2/gmp/configure OR ../gcc-4.6.2/mpc/configure
