Ok, thanks.
Note that Sergio is the original author of this part of the code introduced with
gdb 8.2 and backported to gdb 8.1.1 [1].

I'm agree on the principle but the change from gdb 8.2 introducing the issue has
been backported to gdb 8.1.x [1] without such GDB PR number (as far I can see).
IIUC, all patches backported to a stable branch must have a GDB PR number.
This is not always the case.

Without the fix provided by Sergio (Thanks!) we can't build gdb with a musl
toolchain, so gdb 8.1.x and gdb 8.2.x remain unfixed.

I'll create the GDB PR but all explanations of the issue have been provided on
the mailing list by gdb developers and maintainers.
