Subject: [Driver][Fuchsia] Pass --hash-style=gnu to the linker
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7a3bb94f5b9ad1196634f2710e27dc7ff33c44eb;p=clang

[Driver][Fuchsia] Pass --hash-style=gnu to the linker

The .gnu_hash format is superior, and all versions of the Fuchsia
dynamic linker support it.
