Subject: [PATCH] Do not use --hash-style=both for building glibc shared Subject: [PATCH] force --hash-style=both to keep compatibility with old niche
objects software
The comment indicates that --hash-style=both was used to maintain
compatibility with static dlopen, but we had many internal ABI
changes since then, so this compatiblity does not add value anymore.
