So, your patch was merged in upstream gensio:

  https://github.com/cminyard/gensio/commit/cd7fcd3197722910bfe6be3da4f55b28b8880dc3#diff-8afe8fc980005e7f95dba9eb6fd3747c

Which is now part of the 2.0.1 version of gensio that Buildroot is
using.

However, upstream has applied another patch on top, which drops the
Libs.private entry of your .pc.in:

  https://github.com/cminyard/gensio/commit/6f9ac3bca6dd17f12fc319d888d0875814a07878#diff-8afe8fc980005e7f95dba9eb6fd3747c

In Buildroot, we have added a work-around to link against openssl in
ser2net:

  https://git.buildroot.org/buildroot/commit/package/ser2net?id=a5feea5ea3c3e8b0c8c7e92ec5cefb145215d2c6

So, ideally this work-around should no longer be needed. And indeed, it
does build fine without it. But how come it works since openssl is not
in gensio.pc Libs.private ?

Could you have a look at this whole story ?

Thanks,

Thomas
