The problem was that it tried to use system's libtool (which was for i686-pc-linux-gnu). Removing the patch from patchset makes it work.
Is it possible to remove that patch from the patchset?

Eh, it's not crosscompile-specific at all, there's tons of duplicates [1] for this issue without any crosscompile, because LIBTOOL is missing --tag=CC in Makefile...

I should have said clearer. I knew about --tag=CC but after i patched it to support --tag=CC it still failed because it tried to use i686-pc-linux-gnu-gcc as linker.

removing the patch to satisfy the cross-compiling crowd isnt really worth it

better to just redo the whole build system ... but that gets us back to the fact that the jpeg package has a friggin dead upstream

I have exactly the same problem when cross compiling media-libs/jpeg-6b-r8.
After a quick look at patch applied to libjpeg it seems that this pacth: 06_all_jpeg-libtool.patch is responsible of the bug.
As a matter of fact, if I use ./libtool in libtool-wrapper instead of libtool, everything is ok. So I suggest to modify the patch to use ./libtool in libtool-wrapper.

Try >=media-libs/jpeg-7, appears to have more recent autotools ...
