+Subject: [PATCH] lib*: Remove i*86 march overrides
+
+OE does not pass the '--with-arch' option to gccs configure, as such
+some gcc-runtime libraries try to override the value of '-march' and
+'-mtune' which OE already provides. This causes conflicts with other
+i*86 instruction/architecture flags (e.g. -msse* and -mfpmath=*).
+Additionally this caused the following libraries to be built with less
+optimized tune configurations.
+
+Upstream suggests that this should be detecting or otherwise checking if
+the target supports the desired functionality before overriding.
+
+    https://gcc.gnu.org/legacy-ml/gcc-patches/2016-04/msg01344.html
+
+libatomic also overrides the '-march' specifically for IFUNC objects.
+OE already supplies the correct march flag, so remove setting.
+
+Upstream-Status: Inappropriate [OE Specific]
