uClibc doesn't build with the upstream binutils 2.32.x and gcc or1k port due to the following error: LD libuClibc-1.0.31.so /opt/openrisc--uclibc--bleeding-edge-1/lib/gcc/or1k-buildroot-linux-uclibc/9.2.0/../../../../or1k-buildroot-linux-uclibc/bin/ld: libc/libc_so.a(or1k_clone.os): pc-relative relocation against dynamic symbol __syscall_error See: https://gitlab.com/kubu93/toolchains-builder/-/jobs/270854456 This error message come from a new check in binutils 2.32.x: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff;h=f2c1801f6255a3f9f483ae2f07c7d7da0ddae4af This issue has been reported on the uClibc-ng mailing list: https://mailman.uclibc-ng.org/pipermail/devel/2019-August/001885.html Since gcc 9.1 needs binutils 2.32.x or later to build successfully for or1k, there is no binutils version left that can build gcc 9.1 and uClibc. For now, disable uClibc if gcc 9.1 is used for or1k.
