Subject: [Driver] Use -Bstatic/dynamic for libc++ on Fuchsia
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e49c5834832d96f8b3b3f118ffbb97ca22a9c384;p=clang

[Driver] Use -Bstatic/dynamic for libc++ on Fuchsia

-static relies on lld's behavior, but -Bstatic/dynamic is supported
across all linkers.
