From: Artem Savkov <asavkov@xxxxxxxxxx> [ Upstream commit 61fc5e66f755db24d27ba37ce1ee4873def1a074 ] lld produces "fast" style build-ids by default, which is inconsistent with ld's "sha1" style. Explicitly specify build-id style to be "sha1" when linking liburandom_read.so the same way it is already done for urandom_read.
