[Buildroot] [PATCH 4/8] vlc: remove dependency on C library

[Romain Naour <romain.naour@gmail.com>]

Thomas, All,

Le 18/01/2016 21:24, Thomas Petazzoni a ?crit :
> vlc uses <spawn.h> which was not available in old uClibc
> versions. However, since we are removing support for uClibc 0.9.33, we
> can get rid of such dependency. In addition, <spawn.h> is provided by
> musl, and therefore VLC can be enabled with this C library.
> 
> Consequently, this commit completely removes any C library dependency
> for the vlc package. The only special case that needs to be handled is
> the Blackfin external toolchain from Analog Devices, which still uses
> an old uClibc version that doesn't provide <spawn.h>.

> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
