Comment:
I tried building with `./xbps-src -a armv6l-musl -C pkg ghostscript`. I found something interesting in the ghostscript Makefile:
```
# Define install location for 'cups' device/filter support    
CUPSLIBS=
CUPSLIBDIRS=
CUPSSERVERBIN=
CUPSSERVERROOT=
CUPSDATA=
CUPSPDFTORASTER=0

SHARE_LCUPS=1
LCUPS_NAME=cups
LCUPSSRCDIR=./cups
LCUPSBUILDTYPE=
CUPS_CC=$(CC)

SHARE_LCUPSI=1
LCUPSI_NAME=cupsimage
LCUPSISRCDIR=./cups
CUPS_CC=$(CC)
```

If I build with `./xbps-src -C pkg ghostscript` I get this instead:
```
# Define install location for 'cups' device/filter support    
CUPSLIBS=cups
CUPSLIBDIRS=
CUPSSERVERBIN=/usr/lib/cups
CUPSSERVERROOT=/etc/cups
CUPSDATA=/usr/share/cups
CUPSPDFTORASTER=1

SHARE_LCUPS=1
LCUPS_NAME=cups
LCUPSSRCDIR=./cups
LCUPSBUILDTYPE=
CUPS_CC=$(CC)

SHARE_LCUPSI=1
LCUPSI_NAME=cupsimage
LCUPSISRCDIR=./cups
CUPS_CC=$(CC)
```
