[Buildroot] [PATCH 1/2] package/libtirpc: fix build with gcc 10

[Petr Vorel]

Hi Thomas,

sorry, previous reply was for the second patch.

I experienced this just when for native build on other distro (this patch was
needed for openSUSE), send with a hope it's useful. But feel free to drop it,
libtirpc is releasing often, now it's libtirpc-1-2-6-rc2. As nobody complains
about it, it can wait till the package release.

Kind regards,
Petr
