[PATCH] D35337: [Solaris] gcc runtime dropped support for .ctors, switch to .init_array

[Fedor Sergeev via Phabricator via cfe-commits]

fedor.sergeev created this revision.

crtbegin.o from gcc toolchain as configured on latest Solaris
(with --enable-initfini-array) does not have support for .ctors.

Clang needs to switch to .init_array. Doing it unconditionally
is fine since older Solaris configurations do support .init_array.
