gpsd does not use STAGING_DIR, so I don't see how gpsd does anything
with that.

# fgrep STAGING_DIR * -r
SConstruct:    'STAGING_DIR',               # OpenWRT and CeroWrt

It just passed through STAGING_DIR.

scons does nothing with it either:

# fgrep STAGING_DIR /usr/lib64/python3.6/site-packages/SCons/ -R
# 

So I don't see how gpsd/scons can make a mess out of it.

Yup.  That is what they are for.  Most distros use them with gpsd.

Uh, I'll leave your software to you.

In this case, what is "it", if not buildroot?  That is not part of gpsd.
gpsd/scons knows nothing of STAGING_DIR.

Yes, old news.

Dunno, but the STAGING_DIR confuses the issue, Fix it first.

Nope.  See above.  You are passing that to gpsd/scons when you should not.
