uClibc doesn't build with the upstream binutils 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
For now, disable uClibc if gcc 9.1 is used for or1k.
