Subject: [PATCH][GCC] arm: Optimize arm-mlib.h header inclusion (pr108505).

Hello,

I have committed a fix [1] into gcc trunk for a build issue mentioned in pr108505 and
latter received few upstream comments proposing more robust fix for this issue.

In this patch I'm addressing those comments and sending this as a followup patch.

Regression tested on arm-none-eabi target and found no regressions.

Ok for master?

Srinath.
