main/strace: fix pt_regs collision on ppc64le

Browse Source 
strace build requires <linux/ptrace.h> and it includes <asm/ptrace.h>
that, by its turn, defines the pt_regs struct. However the same struct
is also define in <bits/user.h> from musl-dev, creating therefore a
conflict. A solution is to add the __ASSEMBLY__ guard so pt_regs struct
from <asm/ptrace.h> is not include twice, avoiding the collision in
question.

There is no other way to worki around that issue on Musl since it does
not include the linux headers and hence has to define again the pt_regs
struct in user.h and the name clashes. In glibc, for instance, user.h
includes <asm/ptrace.h> from kernel and does not redefine it.

Also Musl community has no better solution at the moment for this issue
on ppc, so basically nothing change since [1].
