[Pkg-javascript-devel] Bug#1109746: node-webfont: FTBFS with lto enabled [PATCH]

[Gianfranco Costamagna]

Source: node-webfont
Version: 11.4.0+dfsg2+~cs35.7.26-13
tags: patch

Hello, looks like when lto is enabled by default your package FTBFS due to emscripted not understanding the lto flags. While probably emscripten is faulty here, I already found some hacks in the patch removing other flags, so I just adapted it to make sure lto is disabled unconditionally.

Please apply the patch when convenient.

Gianfranco
