Something is weird: the code above tries to create the file
    /m4/libuv-extra-automake-flags.m4

That is, in a sub-dir named 'm4' at the root of the filesystem hierarchy.

The code is about creating $(@D)/m4/libuv-extra-automake-flags.m4 so
this should create a file in the package source tree (the $(@D) part.)

Can you check that your Buildroot tree is correct (I just checkedc mine,
which is master from a few minutes ago, and it is fine.)

Yann E. MORIN.
