package/musl: fix conflict with riscv kernel headers
Add two upstream patches fixing musl vs kernel headers conflict. This fixes build of strace for risc64 at it happens to use headers from both sources. Modify patch #3 to leave a single newline in user.h. Otherwise 'patch -E' in apply-patches.sh deletes user.h instead of leaving it empty. Fixes (strace): http://autobuild.buildroot.net/results/ac32e83dc5eb5ce2809fc4b9d11f540dbdae9ed6/ Cc: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>

+Subject: [PATCH] fix risc64 conflict with kernel headers
+
+Rename user registers struct definitions to avoid conflict with the
+asm/ptrace.h kernel header that defines the same structs. Use the
+__riscv_mc prefix as glibc does.

+Subject: [PATCH] remove riscv64 bits/user.h contents
+
+the contents conflicted with asm/ptrace.h. glibc does not provide
+anything in user.h for riscv, so software cannot be depending on it.
+
+simplified from patch submitted by Baruch Siach.
+
+[ baruch: add empty line so that 'patch -E' doesn't delete user.h ]
