You should also apply the following patch:

diff --git a/package/perl/perl.mk b/package/perl/perl.mk
index fbe7ba9..4e6f50b 100644
--- a/package/perl/perl.mk

                -Duseshrplib \

Otherwise, the build fails with:

/home/thomas/projets/buildroot/output/host/usr/bin/arm-linux-gnueabihf-gcc -l gcc_s -fstack-protector -o miniperl \

[...]

with certain toolchains.

Also, on the target there is a usr/bin/perl and a usr/bin/perl5.x.y
files. One is a hardlink to the other, but it is always a bit
disturbing to see two big files of the same size. Shouldn't we replace
that by a symlink instead, which is more obvious?

Thanks!
