[ARM] Fix NULL dereference of march_ext_opt
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.

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