In theory, the following should produce a usable library:

eu-readelf -s /usr/lib64/mysql/libmysqlclient_r.so.16.0.0 |
./mysql_filter.gawk > hack.c
gcc $(rpm --eval %optflags) -fPIC -shared -fno-toplevel-reorder
-Wl,-soname,libmysqlclient_r.so.16 -Wl,--filter,libmysqlclient.so.16
hack.c -o libmysqlclient_r.so.16

but in practice, it gives me:

/usr/bin/ld: libmysqlclient_r.so.16: version node not found for symbol
sf_malloc_mem_limit@@libmysqlclient_16
/usr/bin/ld: failed to set dynamic section sizes: Bad value
collect2: ld returned 1 exit status

and nobody on the internet has any idea what that error means.
