On some systems, the default echo command doesn't handle the -e option and the output looks like this (arm64 build):

-ne Emit Tests for alsa

-ne Emit Tests for amd-pstate

-ne Emit Tests for arm64

This is for example the case with the KernelCI Docker images e.g. kernelci/gcc-10:x86-kselftest-kernelci. To avoid this issue, use printf which handles escape characters as a standard feature and is more widespread among modern shells.

The output is now formatted as expected (x86 build this time):

Emit Tests for alsa Emit Tests for amd-pstate Skipping non-existent dir: arm64
