Hi Andrew,
Can you please drop commit 35c9dcde4ecb ("selftests: exec: make
binaries position independent")? It looks like it's broken under certain
conditions, and what's more, it seems it's been subtly half-broken since
commit 4d1cd3b2c5c1 ("tools/testing/selftests/exec: fix link error")
too. (Using -static changed the nature of the test since now it doesn't
have an INTERP program header.)
I'll be working to fix it up.
Thanks!
-Kees
