[PATCH] doc/user_manual.md: update ISAR_CROSS_COMPILE variable in SDK part

[srinuv...@siemens.com]

From: Srinuvasan A <srinuv...@siemens.com>

With the present documentation the SDK is not generated properly for
foreign architectures, basically SDK_TOOLCAHIN not picking the proper
toolchain due to mode is not properly set for foreign architecture.

Set ISAR_CROSS_COMPILE by 1 in local.conf to get the correct mode for
foreign architecture.

Unrelated changes, also below. Also, you missed another case under
"Build statistics collection".

And ".." can still be confusing here (and below). Maybe rather

"/path-to-isar/scripts/..."

foreign architectures, basically SDK_TOOLCAHIN not picking the proper
toolchain due to mode is not properly set for foreign architecture.

Set ISAR_CROSS_COMPILE by 1 in local.conf to get the correct mode for
foreign architecture.

Update the path of scripts instead of relative path for accessing files
from isar directory.
