On arm64 musl systems, <asm/ptrace.h> from linux-headers-4.20 conflicts with <signal.h> from musl-1.1.21 if they are both included in the same compilation unit. This causes issues when compiling sys-apps/sandbox: libtool: compile: aarch64-linux-musl-gcc -DHAVE_CONFIG_H -I. -I/var/tmp/portage/sys-apps/sandbox-2.13/work/sandbox-2.13 -DETCDIR=\"/etc\" -DLIBSANDBOX_PATH=\"/usr/lib\" -DSANDBOX_BASHRC_PATH=\"/usr/share/sandbox\" -D_REENTRANT -O2 -Wall -Winvalid-pch -fdata-sections -ffunction-sections -fno-builtin-calloc -fno-builtin-malloc -fno-builtin-realloc -c /var/tmp/portage/sys-apps/sandbox-2.13/work/sandbox-2.13/headers.h -fPIC -DPIC -o libsbutil/.libs/headers.h.gch.o In file included from /usr/include/asm/ptrace.h:26, from /var/tmp/portage/sys-apps/sandbox-2.13/work/sandbox-2.13/headers.h:152: /usr/include/asm/sigcontext.h:28:8: error: redefinition of 'struct sigcontext' struct sigcontext { ^~~~~~~~~~ In file included from /usr/include/signal.h:48, from /var/tmp/portage/sys-apps/sandbox-2.13/work/sandbox-2.13/headers.h:63: /usr/include/bits/signal.h:18:16: note: originally defined here typedef struct sigcontext { ^~~~~~~~~~ This is resolved upstream by these two commits: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ee1b465b303591d3a04d403122bbc0d7026520fb https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=9966a05c7b80f075f2bc7e48dbb108d3f2927234
I might add this to the overlay, since it has been fixed upstream for linux-headers-5.x - does this happen only with linux-headers-4.20?

Feel free to reopen if your still having problems. I have tested with a stable musl/linux-headers and have not seen any problems.
