[ptxdist] [PATCH] dump1090fa: New package. Version 6.1

[Christian Melki <christian.melki@t2data.com>]

dump1090 from FlightAware is an ADS-B (Automatic Dependent Surveillance-Broadcast).
ADS-B is used by aircrafts to signal their presence.
Using an RTL (very cheap) based SDR, you can easily build your own ADS-B decoder.

+Subject: [PATCH] Allow env vars (not only command line overrides) to set
+ CPUFEATURES_{ARCH,UNAME}. Change CPUFEATURES_{ARCH,UNAME} defaults to use
+ {ARCH,UNAME} values.
