[gentoo-alt] Re: [PREFIX][solaris] no more LDFLAGS and LD_RUN_PATH in profile.bashrc

[Michael Haubenwallner]

Hi,

tried a different way with exciting success:

Attached sys-devel/binutils-2.16.1-r3.ebuild creates a wrapper script
around the real linker, which always appends to ld-commandline:
-rpath=$EPREFIX/lib:$EPREFIX/usr/lib

So I can remove setting LD_RUN_PATH and LDFLAGS completely from
sunos/profile.bashrc, going around any "whether need -Wl," and "LDFLAGS
are not passed to linker" issues.

Have remerged system+vim+svn, and all binaries really have good
DT_RUNPATH encoded now :-)

Thoughts ?
