+Fix musl build
+
+Downloaded from:
+https://github.com/openwrt-mirror/openwrt/blob/f22d5e25660106a48727c7aa5d1a73e4171a7987/package/devel/oprofile/patches/100-musl.patch
+after I found a hint for the patch here:
+http://patchwork.openembedded.org/patch/112675/
+
+Because openwrt removed the oprofile package from their repo last week
+https://github.com/openwrt-mirror/openwrt/commit/aaf46a8524e138e1673a398e8d2dd9357405b313#diff-fe14456f94abf436d997e2c01c10f3bd
+I decided to put this patch into the buildroot repo instead of adding
+_PATCH to oprofile.mk
