Subject: [PATCH] Fix building on musl-libc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

libgtop fails to build on musl libc, due to the header
resulting in the headers that would be loaded for libc 5 being
loaded on musl libc.
musl defines headers which are also defined in linux-headers'
in.h, causing redefinition errors.
