+Subject: [PATCH] modutils: remove special handling of uClibc
+
+Commit 3a45b87ac36f (modutils: support finit_module syscall) introduced
+macro finit_module. But it is not defined for uClibc.
+
+The compilation for busybox fails for MIPS with:
+With uClibc, we get following build errors:
+
+ modutils/lib.a(modutils.o): In function `bb_init_module':
+ modutils.c:(.text.bb_init_module+0x94): undefined reference to `finit_module'
+ modutils.c:(.text.bb_init_module+0xa0): undefined reference to `finit_module'
+
+We can just use syscall() without any need for the
+uClibc wrappers.
+
+Newer versions of uClibc-ng (>1.0.20) will remove the
+module syscall wrappers.
+
