[Tarantool-patches] [PATCH v1] Block linker flag '--no-undefined'

[Igor Munkin]

Sasha,

Thanks for the patch! I added the patch from upstream to point several
nits.

================================================================================

    test: fix for OpenSuSE tests build

    Found that OpenSUSE toolchain adds '--no-undefined' linker flag leading

both in commit subject and commit message.

    to fails while building tests. The changes suppress this flag since
    dynamic libraries are loaded via Tarantool executable and use its
    symbols. So it is completely OK to have undefined symbols at build time.
    Feel free to adjust it on your own.

Typo: The last line was for you, not for the message, please drop it.


    Needed for #4562

Minor: you can use the same part from the commit message, but I'm not
insisting. It just looks rational to me.

Please adjust the indentation considering the code nearby: use 4 spaces
instead of tab.
