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

[Thomas Petazzoni]

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>.
