+Subject: [PATCH] networking/libiproute: use <linux/if_packet.h> instead of
+ <net/if_packet.h>
+
+The musl C library doesn't provide the <net/if_packet.h> since the
+corresponding kernel headers <linux/if_packet.h> already provides the
+necessary definitions. Replacing <net/if_packet.h> by
+<linux/if_packet.h> also removes the need to include
+<netpacket/packet.h>
+
+This commit fixes the build of iplink with the musl C library.

+
+However, arch/$(ARCH)/Makefile gets included *after* Makefile.flags,

+Fix this by including arch/$(ARCH)/Makefile *before* Makefile.flags.

+
+As stated by the gcc documentation, the SPARC architecture has a
+limited GOT size, which prevents moderately large binaries to be built
+with -fpic, and -fPIC is necessary. From gcc's documentation:
+
+'-fpic'
+     Generate position-independent code (PIC) suitable for use in a
+     shared library, if supported for the target machine.  Such code
+     accesses all constant addresses through a global offset table
+     (GOT).  The dynamic loader resolves the GOT entries when the
+     program starts (the dynamic loader is not part of GCC; it is part
+     of the operating system).  If the GOT size for the linked
+     executable exceeds a machine-specific maximum size, you get an
+     error message from the linker indicating that '-fpic' does not
+     work; in that case, recompile with '-fPIC' instead.  (These
+     maximums are 8k on the SPARC, 28k on AArch64 and 32k on the m68k
+     and RS/6000.  The x86 has no such limit.)
+
+'-fPIC'
+     If supported for the target machine, emit position-independent
+     code, suitable for dynamic linking and avoiding any limit on the
+     size of the global offset table.  This option makes a difference on
+     AArch64, m68k, PowerPC and SPARC.
+
+With a limit of 8KB on SPARC, we quickly reach this limit, and we hit
+it when building Busybox on SPARC/SPARC64 with the
+CONFIG_BUILD_LIBBUSYBOX=y option enabled.
+
+Therefore, this commit redefines ARCH_FPIC as -fPIC on sparc and
+sparc64 to solve this issue.
