[Buildroot] [PATCH 2/3] package/dvb-apps: is not parallel-safe

[Yann E. MORIN]

This is invisible because the timings make it excessively difficult to
hit, but the Makefile is inherently flawed for parallel build, as it
contains:

    $(objects): atsc_psip_section.c atsc_psip_section.h

    atsc_psip_section.c atsc_psip_section.h:
        perl section_generate.pl atsc_psip_section.pl

and the perl script section_generate.pl will create both the .c and .h
files in one go, but given the construct above, there can be two such
script that run in parallel, which can clobber the generated .c and/or
.h files.

So, make dvb-apps a MAKE1 package.

The time to build increased by one third, from ~7.5s to ~10s, on a
core-i7 quad-core, which is not much in the end, and totally acceptable.
