OK well, have found that LDFLAGS is the right way of doing this.

As "emerge --info" shows nothing sat for LDFLAGS I guess "gentoo" is not
using any value for LDFLAGS.

But then again what is then the default value of LDFLAGS that is safe for
most emerges.

I'm trying to go with..
LDFLAGS="-Wl,-O1 -Wl,--as-needed"

Anyone having experience with LDFLAGS ?

Can't say personal experience, but found these two threads in the Gentoo
forums that may be able to assist:

http://forums.gentoo.org/viewtopic-t-316445.html
http://forums.gentoo.org/viewtopic-t-316417.html

I'm interested in this too... I may give it a go and get back to you on
it...

HTH,
