New Revision: 269585

URL: http://llvm.org/viewvc/llvm-project?rev=269585&view=rev
Log:
Disable LIBCXX_ENABLE_ABI_LINKER_SCRIPT for static library builds.

This option is geared towards shared library builds and causes static
library builds to fail if not explicitly disabled.

This patch fixes PR27706: https://llvm.org/bugs/show_bug.cgi?id=27706

Thanks rgoodfel at isi.edu for the catch.
