[Problems linking to zlib corrected if zlib is linked with -Bsymbolic-functions]
when doing some research, it appears Ubuntu has it by default for
some time.

   This is currently only a suggestion and/or request for comments.
Some extra detail in https://bugzilla.redhat.com/show_bug.cgi?id=1778234
[Request For Comments: -Bsymbolic-functions in LDFLAGS by default]

   Basically, there would be a few issues, most times in broken code,
and the valid cases could be worked around removing -Bsymbolic-functions.

   The biggest advantages are far less relocations, for example, that
should mean faster load time, and avoids several issues with symbols
being clobbered by symbols from another library.

If I understand correctly then it will also mean that LD_PRELOAD will
not work for any call made from the library to itself, but would still
work for calls made from other libraries.
