Thanks, it is reassuring!

Regarding the install I only specify the home dir as the target
(PREFIX) and make install creates subdirs below that where it stuffs
files.
If I knew the locations affected I could just rm -r them before
running make install. But I don't, so this is why I ask.

I did not mention why I need to go from ARMv7 to ARMv6, but it is
because I found that binaries generated by my ARMv7 installation will
not run on all Raspberries. On RPiZero I get an instant exception,
whereas if it was compiled on the RPiZero itself ir runs fine.
On the Zero I installed using the v6 switch because that device is an
ARMv6. And that binary runs on *all* RPi I have tested on.

That is why I want my main RPi dev box to be converted to use ARMv6
instruction set.

Final question:
Lazarus is built (and rebuilt numerous times) using the ARMv7
compiler. Do I need to rebuild Lazarus (and all the installed
packages) too if I switch to a different fpc compiler?
