[langdale 40/41] perfetto: pass TUNE_CCARGS to use machine tune

[Armin Kuster <akuster808@gmail.com>]

From: Markus Volk <f_l_k@t-online.de>

We already tried to pass -mfloat-abi=hard if the machine can use it, but since
no floating-point-unit was defined it got stubbed out and the result was, that
only arm targets configured for softfp were able to build perfetto.

Simplify by passing ${TUNE_CCARGS} to ensure, we always use the features, the
machine was configured for.

Also, do not use sed to remove the hardcoded -mfpu=neon entry. If this really
turns out to be problematic, we need to patch it out to avoid not having a
floating-point-unit again.
