Setting it up...ERROR: could not relocate /buildarea/raid5/hjia/community/lat_github_090816/build-3/tmp/deploy/sdk/sdk-3/sysroots/x86_64-pokysdk-linux/usr/lib/libpsx.so.2.54, interp size = 93 and 134 is needed. ... Since upstream libcap applied commit [ee3b25c Support simply executing the built shared libraries.][1], it manually append interp section to shared libraries.
