Bug description:
[Impact]
* Gdb can't set some breakpoints in ld.so on armhf when libc6-dbg is
not installed.
[Test Plan]
* Check that ld.so is not stripped on armhf:
$ /lib/*/ld-2.31.so
libc6/lib/arm-linux-gnueabihf/ld-2.31.so: ELF 32-bit LSB shared object, ARM,
EABI5 version 1 (SYSV), dynamically linked,
BuildID[sha1]=e20a43bff0c4d2aa7f508c93eadad973ea0c0af9, with debug_info, not
stripped
* Check that ld.so is stripped on amd64:
$ file /lib/x86_64-linux-gnu/ld-2.31.so
/lib/x86_64-linux-gnu/ld-2.31.so: ELF 64-bit LSB shared object, x86-64,
version 1 (SYSV), dynamically linked,
BuildID[sha1]=ea85fcb25ee4c4c9e7b180924ab4a44257a9547a, stripped
[Where problems could occur]
* The fix is not stripping ld.so on armhf. Not stripping it comes with
a notable increase in file size and it may be performance critical
109K stripped vs 1.3M unstripped. Accidentally ld.so could be left
unstripped on other architectures, but the test plan covers checking
that, at least on amd64. Other than those not stripping ld.so should
not cause any issue.
