[PATCH AUTOSEL 6.6 3/3] selftests/alsa: Fix circular dependency involving global-timer

[Sasha Levin <sashal@xxxxxxxxxx>]

From: Li Zhijian <lizhijian@xxxxxxxxxxx>

[ Upstream commit 55853cb829dc707427c3519f6b8686682a204368 ]

The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular
dependency on the global-timer target due to its inclusion in
$(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency
warning during the build process.

To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been
replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change
ensures that libatest.so is built before any other targets that require it,
without creating a circular dependency.

This fix addresses the following warning:

make[4]: Entering directory 'tools/testing/selftests/alsa'
make[4]: Circular default_modconfig/kselftest/alsa/global-timer <- default_modconfig/kselftest/alsa/global-timer dependency dropped.
make[4]: Nothing to be done for 'all'.
make[4]: Leaving directory 'tools/testing/selftests/alsa'
