Hi,
I am trying to build a toolchain for an embedded 486 board.
I am using OSELAS 1.99.3 and created a new ptxconfig from
i586--unknown-linux-gnu_gcc-4.1.2_glibc-2.5_binutils-2.17_kernel-2.6.18.ptxconfig
renamed it to
i486--unknown-linux-gnu_gcc-4.1.2_glibc-2.5_binutils-2.17_kernel-2.6.18.ptxconfig
and changed the internal references from '586' to '486'.
I am using ptxdist-1.99.11 to build the toolchain.
During the build occurred an error in target:glibc-crt.prepare

Any ideas on how to fix this ?
Best regards,
