rtla: Fix Makefile when called from -C tools/
Sedat Dilek reported an error on rtla Makefile when running:
$ make -C tools/ clean
[...]
make[2]: Entering directory
'/home/dileks/src/linux-kernel/git/tools/tracing/rtla'
[...]
'/home/dileks/src/linux-kernel/git/Documentation/tools/rtla'
/bin/sh: 1: test: rtla-make[2]:: unexpected operator <------ The problem
rm: cannot remove '/home/dileks/src/linux-kernel/git': Is a directory
make[2]: *** [Makefile:120: clean] Error 1
make[2]: Leaving directory
This occurred because the rtla calls kernel's Makefile to get the
version in silence mode, e.g.,
$ make -sC ../../.. kernelversion
5.19.0-rc4
But the -s is being ignored when rtla's makefile is called indirectly,
so the output looks like this:
$ make -C ../../.. kernelversion
make: Entering directory '/root/linux'
5.19.0-rc4
make: Leaving directory '/root/linux'
Using 'grep -v make' avoids this problem, e.g.,
$ make -C ../../.. kernelversion | grep -v make
5.19.0-rc4
Thus, add | grep -v make.
