+The angr test suite performs analysis on several pre-compiled binaries
+to ensure its binary analysis capabilities are working as intended.
+Some of these binaries are also executed as part of the test suite to
+test if the simulation engine provided by angr results in the same
+output as native execution of the binary.
+
+For Guix, this files as the glibc shared objects cannot be found.
+Additionally, we don't really want to execute pre-compiled binaries
+on Guix, hence we disable those tests.
