openjdk-7: fix compile errors with current poky master (gcc6)

Using the current poky master openjdk-7 wasn't buildable. This patch
fixes those problems by adding three more patches to openjdk-7.

These patches basically add/fix GCC6 support. Furthermore the
LDFLAGS_HASH_STYLE variable (which was removed by the
icedtea-crosscompile-fix.patch) is re-introduced and set to "both" for
compatibility reasons.

Following two patches were originally written by Abdur Rehman and taken
from meta-mentor [1]:
	icedtea-flags-to-compile-with-GCC-6.patch
	icedtea-specify-overloaded-variant-of-fmod.patch
