gold: warning: wildcard match appears in both version 'GLIBC_2.29' and
'GLIBC_2.30' in script
The example is derived from glibc. I think the warning should be suppressed:
GLIBC_2.29 { global: xxx; yyy; local: *; }; can be used to keep xxx@GLIBC_2.29
yyy@GLIBC_2.29 while localizing other *@GLIBC_2.29 non-default version symbols.
It's perfectly fine for multiple version nodes to localize their non-default
version symbols.
