[Buildroot] [PATCH 2/3] support/scripts: don't require gawk to generate glibc gconv modules

[<yann.morin@orange.com>]

When a subset of the glibc gconv modules installed, we eed to generate a
trimmed-down list of available modules. We currently use gawk for that.

However, we are not using any GNU extension in that awk script, and it
happens to work as expected when using mawk (which has no GNU
extension).

Commit 11c1076db9a5 (toolchain: add option to copy the gconv libraries)
did not explain why it used gawk explicitly, and given the age for that
commit, we doubt we'd be able to have the involved participants recall
anything from that period...

Besides, gawk is not a requirement for Buildroot.

Switch over to using plain awk.
