selftests: find echo binary to use -ne options
[ Upstream commit 4ebe33398c40c1118b4d8546978036c0e0032d1b ]
Find the actual echo binary using $(which echo) and use it for
formatted output with -ne. 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. With the actual echo
binary (e.g. in /bin/echo), the output is formatted as expected (x86
build this time):
Emit Tests for alsa
Emit Tests for amd-pstate
Skipping non-existent dir: arm64
Only the install target is using "echo -ne" so keep the $ECHO variable
local to it.
