Hi,

Commit 4d354d8b8932d450c77fd52f3501662827523014 introduced a NULL
pointer dereference by replacing a pointer assignment by a pointer
dereference assignment without adding a NULL pointer check. This patch
fixes it.

ChangeLog entry is as follows:

*** gas/ChangeLog ***

2018-03-02  Thomas Preud'homme  <thomas.preudhomme@arm.com>

	* config/tc-arm.c (md_begin): Add NULL pointer check before
	dereferencing march_ext_opt.

Committed as obvious.

Best regards,

Thomas
