Recent versions (> 5.33) of `file` report liblto_plugin.so as
executable:
$ file liblto_plugin.so
liblto_plugin.so.0.0.0: ELF 64-bit LSB pie executable ...
Which then leads to improper packaging of the plugin, resulting in the
broken compiler:
configure: checking whether the C compiler works
mips-openwrt-linux-musl/bin/ld: liblto_plugin.so: error loading plugin: liblto_plugin.so: invalid ELF header
As the LTO compiler plugin library is incorrectly packaged as SDK
executable:
$ head -1 ~/staging_dir/toolchain...libexec/gcc/.../liblto_plugin.so
#!/usr/bin/env bash
Fix this by filtering out shared libraries from the patching.
