debian has a linux-libc-dev and libc6-dev
(glibc) depends on it

i guess other systems are similar, so you
have a /usr/include/linux directory on a
glibc system

musl does not depend on the linux headers

and you cannot use the host's /usr/include
with musl, you need to install all the
dependencies of redis (in this case the
linux headers) to a musl specific prefix

i assume the arch specific asm dirs are included

(the contents of include/ and arch/$ARCH/include/
are needed)

yes that's probably wrong

before sending a bugreport:
export LC_ALL=C;

(it's enough to set LC_MESSAGES but LC_ALL is shorter)
