<pre>When porting the sanitizers to FreeBSD/arm64 I found the tests failed to run
with the following error:
/lib/libc.so.7: Undefined symbol "__progname"
I tracked this down to the use of --dynamic-list with lld. When I remove these
arguments from the linker command line the test runs without the error.
Building with ld.bfd, but with --dynamic-list also runs correctly.
It seems the issue is lld fails to put __progname in the .dynsym section. This
comes from crt1.o, and libc expects this to be exported from the main program.</pre>
