[Buildroot] [git commit] package/strace: disable libmpers with musl toolchains

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=7892a778b8bed72202db9641c2649825852148b0
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

strace bundle some kernel headers to build libmpers, this mixes userspace
headers and kernel headers which break the build with musl.
The stddef.h from gcc is used instead of the one from musl.

Disable libmpers for musl toolchains.
