However this is not true when building a PIE binary, which some toolchains (Ubuntu) configure as the default. When compiling btitest with such a toolchain, it will create a dynamically linked binary, which will probably fail some tests, as the dynamic linker might not support BTI: =================== TAP version 13 1..18 not ok 1 nohint_func/call_using_br_x0 not ok 2 nohint_func/call_using_br_x16 not ok 3 nohint_func/call_using_blr .... =================== To make sure we create static binaries, add an explicit -static on the linker command line. This forces static linking even if the toolchain defaults to PIE builds, and fixes btitest runs on BTI enabled machines.

Since BTI support is still being rolled out in distributions these tests are built entirely free standing, no libc support is used at all so none of the standard helper functions for kselftest can be used and we open code everything. This also means we aren't testing the kernel support for the dynamic linker, though the test program can be readily adapted for that once it becomes something that we can reliably build and run.
