Comment 4 for bug 1927192

It's ok to strip glibc/ld.so on armhf, but then gdb needs to be able to find the debug symbols.

For impish,

 - call dh_strip in glibc with current debhelper, not compat 8,
   so that the build-id's are resolved by build file system
   layout, not the original file names. That's already done in
   glibc 2.33-0ubuntu6

 - let the gdb build depend on libc6-dbg on armhf, also let
   gdb depend on libc6-dbg on armhf, instead of recommending
   it.

The alternative is not to strip glibc's ld.so on armhf, as Luis suggested.
