Maybe you could elaborate on how did you come to the conclusion that your
LDFLAGS are ignored, which ones are ignored and where's the problem. The above
cryptic stuff unfortunately doesn't explain anything.

Some LDFLAGS can change existence of some sections in ELF files. I have such (at least) 2 flags in my LDFLAGS and one of them always change existence of some sections when isn't ignored.
I changed /usr/lib/portage/bin/prepstrip, so that it now additionally runs readelf and grep and copy the output to the log file.
I perform some tests (reading emerge logs) and >99,5% of results are correct.

All.

Ignoring LDLFAGS increases files sizes and decreases performance.

As of ruby-1.8.6, we can set EXTLDFLAGS=$LDFLAGS to feed user LDFLAGS to ruby. Something like this:

--- ruby-1.8.6-r1.ebuild        2 Jul 2007 14:50:46 -0000       1.14
+++ ruby-1.8.6-r1.ebuild        23 Aug 2007 14:19:43 -0000

-       emake || die "emake failed"
+       emake EXTLDFLAGS="${LDFLAGS}" || die "emake failed"
 }
 
 src_test() {

Arfrever, can you check if the trick works for you?

It works.

ruby-1.8.6_p36-r4 has been added to the tree. Hopefully it won't pull a new stream of bugs due to bad LDFLAGS usage :)
