I can confirm that with both patches applied (Lance's patch on GCC and
linted's patch on uClibc-ng) I can build a working hello world for ARM
with -fpie --static-pie.
Btw your GCC patch also applies well to GCC 10.3.0. (Tested with Buildroot)

turns out GCC
doesn't currently handle -static-pie with arm, and is not passing the
correct options to the linker. This patch applies onto GCC 12.1 which
fixes that, and I will try to upstream.

One thing that threw me for a while is that the 'file' command in
Debian 10 is apparently too old to know what static-pie is, and
reports it as dynamically linked but without a reference to to the
dynamic linker.
Nice patch! I'm glad to see this feature come to uclibc-ng. I saw you
had a arm64 branch in your repo so would be cool to see that too.
thanks,
Lance
