Subject: Bug #233077 - Add QA check which verifies that LDFLAGS are respected.
 For now this only works when LDFLAGS contains --hash-style=gnu since in this
 case the the elf files should not contain .hash sections and we can use
 scanelf to check whether or not the those sections exist. This adds a
 QA_DT_HASH variable that is analogous to existing QA control variables
 documented in the ebuild.5 man page. There is also a complementary
 QA_STRICT_DT_HASH variable that can be set in make.conf in order to ignore
 QA_DT_HASH settings in ebuilds. Thanks to Arfrever Frehtes Taifersar Arahesis
 for this patch which I've tweaked in just a few minor ways.
