Btw, why we still need these two patches?
It seems that they are in the gcc package since gcc 4.2.4 (i.e ten years)

For 0001-uclibc-conf.patch, why we need to add a new case for
i686-pc-linux-uclibc? what's about other target and libc (musl)?
I believe this can be removed.

0002-arm-softfloat-libgcc.patch was added in 2007 [1] for gcc 4.1.2.
I believe arm soft-float should work out of the box now.

Best regards,
Romain
