Fix aarch64 static linking into shared libraries (see issue #10842 and pull request #11464)
This tries to fix the following link errors on aarch64 when using OpenSSL
3.0.0 alpha 6, compiling it with "no-shared" and -fPIC in CFLAGS, then
trying to use the resulting OpenSSL static libraries in the build of
elfutils, which embed libcrypto.a into libdebuginfo.so, which hides all
symbols (except the libdebuginfod ones) by default:
