Subject: libunwind: requires glibc if arch in powerpc
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1e5f4dcd66807b662f0ffb2bebd0c8bf9bf89c92;p=openwrt%2Fstaging%2Fnbd.git

libunwind: requires glibc if arch in powerpc

libunwind for powerpc depends on getcontext() from libc which musl-libc
does not provide because this API and its friends are supposed to be
"obsolescent" [1,2]
