Documentation for .arch and .cpu directives currently says that it
accepts the same name as -march/-mcpu command-line options respectively.
However it only accept the architecture/CPU part of those options: it
does not accept specifying an extension which is done via
.arch_extension. This patch clarifies that the extension is not
accepted.

ChangeLog entry is as follows:

*** gas/ChangeLog ***

2018-07-25  Thomas Preud'homme  <thomas.preudhomme@linaro.org>

    * doc/c-arm.texi (.arch directive): Clarify that name must not include
    an extension.
    (.cpu directive): Likewise.

Testing: Successfully built the info, PDF and HTML gas documentation.

Is this ok for master?

Best regards,

Thomas
