Not needed here. See the next comment.

This should be:

if BR2_PACKAGE_SQUEEZELITE

config BR2_PACKAGE_SQUEEZELITE_RESAMPLE
	bool "Enable resampling function"
	select BR2_PACKAGE_LIBSOXR
	[..]

endif

Not sure if we need to enable it by default.

libsoxr can be removed here. See next comment.

SQUEEZELITE_DEPENDENCIES += libsoxr

As Thomas Petazzoni assumed RESAMPLE_MP requires OpenMP support. So we
shouldn't enable it by default. Or don't use it at all.

Buildroot usually uses no indention in ifeq (but in define) blocks.

Why do you add only a choice for the resampler option? The Makefile
shows that you can also opt-in DSD support, FFmpeg (for WMA and ALAC
support), Visualizer support and LIRC remote control support.
