linuxdoc-tools-native: Makedoc.sh uses /tmp and fails w/ noexec mount

The Makedoc.sh script uses the following line to set TMPDIR

export TMPDIR=`mktemp -d ${TMPDIR:-/tmp}/ldt.XXXXXXXXXX`;

and then later in the script:

chmod u+x $TMPDIR/linuxdoc

Since TMPDIR is not set the script will default to /tmp and if /tmp
is set to noexec (which is becoming more common), the chmod call fails.

package_ipk.bbclass: Fix SRC_URI whitespace handling

The SRC_URI may contain whitespace, but be otherwise empty.  This can happen
in the case:

MYSRC = ""
MYSRC_arm = "file://myarm.patch"
SRC_URI += "${MYSRC}"

Unless we strip blank spaces, to determine if it is empty, we can end up
generating a "Source: " line which in invalid.  This leads to the error:

  invalid Source: field is speified in the generated CONTROL file
