makepkg adds --as-needed in linking step and that breaks my package?

Hi,
I maintain a PKGBUILD that produced some strange behaviour. If I manually do the steps as written in the PKGBUILD, everything works fine. On the other hand, when I run it with makepkg, the linking step fails, complaining about a lot of "undefined reference"...

I tried to narrow it down, and found that Arch adds the "-Wl,--hash-style=gnu -Wl,--as-needed" flag in the linking step, and the second part is what caused the problem. If I re-run the linking step manually, but removing the "-Wl,--as-needed", it all works. If I instead in the PKGBUILD do a

make LDFLAGS=""

then everything goes dandy too...

Out of curiosity, why would this happen? How can --as--needed break things?

is happening because is a bug in their building,especially at the end where the linking is done.
usually when we have a package that fails we report it upstream and until is fixed we add in PKGBUILD:

export LDFLAGS="${LDFLAGS//-Wl,--as-needed}"

Give what you have. To someone, it may be better than you dare to think.

Thanks!
What kind of bug is expected in this situation? I've found that e.g. Gentoo has a big bunch of collected bug reports, but can't see a patter yet.

There were a few little oddities about the building anyway, I think I'll just just report upstream and see what happens...
