[meta-oe][PATCH] iperf3: add missing "libgcc" RDEPENDS

[michael.opdenacker]

From: Michael Opdenacker <michael.opdenacker@rootcommit.com>

This fixes an issue observed with iperf3 added to core-image-minimal.
The executable starts fine but at the end of a test, issues this error:

yeah patch is ok.
everytime I see a hard dependency on libgcc, I remember that we need
to make it virtual/libgcc or some such
so other toolchains ( clang ) can accommodate its version of stack
