[Buildroot] [PATCH v2] bluez5_utils: new package

[Yann E. MORIN <yann.morin.1998@free.fr>]

Marcin, All,

Thanks for your patch. Here are a few comments below...

So it has a dependency on the Linux kernel headers installed with the
toolchain, right? We now have a way to express this kind of
dependencies:

    depends on BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_4

See the current manual:
    http://nightly.buildroot.org/#dependencies-target-toolchain-options

There's 5.15, now...

Maybe make tests optional?

Why is autoreconf needed? The tarballs do have ./configure.

configure.ac uses PKG_PROG_PKG_CONFIG, so you'd need:
    BLUEZ5_UTILS_DEPENDENCIES += host-pkgconf

Also, configure.ac uses AC_DISABLE_STATIC, so it looks like they do not
intend to support static linking. You'll need in Config.in:
    depends on !BR2_PREFER_STATIC_LIB

Bluez4 has more config knobs: are they no longer applicable to Bluez5?
  - Audio
  - USB support
  - GATT support

Since you mention the subject in the commit log: is there a way to
enable/disable support for BTLE?
