[PATCH] D65668: [Driver][test] Avoid undefined grep in darwin-ld.c

[Hubert Tong via Phabricator via cfe-commits]

hubert.reinterpretcast created this revision.
hubert.reinterpretcast added reviewers: rnk, daltenty, xingxue, jasonliu.
Herald added a project: clang.

question-mark is not a BRE special character.

POSIX.1-2017 XBD Section 9.3.2 indicates that the interpretation of `\?`
as used by rC366282 <https://reviews.llvm.org/rC366282> is undefined. This patch uses an ERE instead.
