+Subject: [PATCH] misc/cgo/testshared: increase size limit in size check
+
+Recently in Fedora we switched binutils ld's separate-code on. This
+led to increased size of binaries, especially on 64k aligned arches.
+For example trivial test binary size grew from 80k to 211k on ppc64le
+tripping the size check(RHBZ#2030308). Therefore adjusting the size limit.
