qt5base: use -device-option to set mkspec variables

Simplify our custom qmake.conf:
  - Include linux_device_{pre,post}.conf to inherit common device
    configuration.
  - Do not add $(STAGING_DIR)/usr/include to include path. It is
    redundant.

In additon to the simplification of code, this change is a preparation
to solve problems occurring when QMAKE_CXX is prepended with ccache path.

Upstream patch is needed by configure to parse device options correctly.
Another upstream patch is needed to remove ARM specific parts from
linux_device_post.conf.

+Subject: [PATCH] configure: Parse -device-option value correctly
+
+The regular expression does not parse correctly when a device option value
+contains the character '=' (e.g. QMAKE_CFLAGS="-D_FILE_OFFSET_BITS=64").
+
+In order to break string at the first equal sign and to simplify code,
+use "cut" command as in other places in configure script.
