Makefile.am: filter -Wl,--no-undefined
Commit 1d14ef82f4a3be741bcdf6b1c6d51ce9dce43567 does not completely fix
the build with python 3.8 as we still get link failure due to
'-z undefs' being ignored by some versions of ld.
Indeed, -z undefs was added by commit
97a232d7335f3bd0231fd9cd39455bde1d563922 in upstream binutils, and this
commit was first present in binutils 2.30.
So any toolchain using binutils version older than that won't have
-z undefs and will build fail on:
/home/buildroot/autobuild/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/5.3.0/../../../../mips-linux-gnu/bin/ld: warning: -z undefs ignored.
/home/naourr/work/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/aarch64_be-linux-gnu/7.3.1/../../../../aarch64_be-linux-gnu/bin/ld: warning: -z undefs ignored.
So filter -Wl,--no-undefined to fix the issue
