[ELDK] [PATCH v2 1/2] META-ELDK: u-boot-mkimage: unbreak U-Boot tools build

[Gerhard Sittig]

building the u-boot-mkimage-native package breaks with the error message

  mxsimage.c:18:25: fatal error: openssl/evp.h: No such file or directory

OpenSSL related header files are not found despite their being present
in the native sysroot

the error can be hidden by libssl-dev packages in the build machine, in
this case the host's header files are used instead (which would result
in building applications against headers that don't match the library
which gets used at runtime, and is as bad)

this change unbreaks compilation of the u-boot-mkimage-native package;
passing both the CC as well as the CFLAGS values within one HOSTCC spec
is done because passing individual HOSTCFLAGS does not work for v2014.01
and results in the error message

  gcc -isystem.../tmp/sysroots/x86_64-linux/usr/include -O2 -pipe -o default_image.o default_image.c -c
  In file included from imagetool.h:12:0,
                   from aisimage.c:8:
  os_support.h:10:22: fatal error: compiler.h: No such file or directory
  compilation terminated.

changes in v2:
- reword and expand the commit message for improved clarity,
  state why passing individual CFLAGS doesn't work
- break the long EXTRA_OEMAKE recipe text line

I'm happy to capitalize sentences in the commit message (assuming that
there is so strong a policy for non-documentation parts), after the
actual change has been verified.  My tests included generic-armv7a-hf,
socfpga and m28evk.
