The format for help text is: one tab, two spaces, the help text.
Also, it is customary to include the upstream location for the package.
If there is no 'homepage', then pointing to the git repo is OK.

This 'comment' should not be indented.

We usally do not 'depends on' libraries, we 'select' them. If the
selected library has dependencies, we inherit the dependencies from that
library. So, you'd get something like:
config BR2_PACKAGE_PIFMRDS
bool "pifmrds"
depends on BR2_arm
depends on BR2_LARGEFILE # libsndfile
select BR2_PACKAGE_LIBSNDFILE
help
FM-RDS transmitter using the Raspberry Pi's PWM.

(see below) Also pass $(TARGET_LDFLAGS).

Are the .wav files really necessary, or are they not just for testing
purposes? If only for testing, do not install them; let the user provide
his own collection of files to play.

Patches should be named package-number-title.patch, so something like:
pifmrds-0000-Makefile-make-it-cross-compile-friendly.patch
Also, patches should contain a standard commit log, something like:
Makefile: make it cross-compile friendly
The current Makefile makes heavy assumption that it is natively
compiled on the RPi.
Fix that so it plays nicely in Buildroot.

You may want to pass the $(LDFLAGS) here:
$(CC) $(LDFLAGS) -o [.....]
and pass LDFLAGS the same way you pass CFLAGS, in the .mk file.
