 Subject: [PATCH] dynbinary: use go cross compiler
 
+MJ: use ${GO} also in "go env" calls, because native go:
+  $ go env GOARM
+  5
+while go cross compiler for my target:
+  $ ${GO} env GOARM
+  7
+this can lead to:
+  error: switch '-mcpu=cortex-a9' conflicts with switch '-march=armv5t' [-Werror]
+
+but even after fixing it to use "better" -march it still doesn't match with -mcpu
+set in our GOBUILDFLAGS, causing e.g.:
+  error: switch '-mcpu=cortex-a9' conflicts with switch '-march=armv7-a+simd' [-Werror]
+
+so drop CGO_CFLAGS/CGO_CXXFLAGS as in OE builds we don't need them
+as long as ${GO} and GOBUILDFLAGS are respected
+
+it was added in:
+https://github.com/moby/moby/commit/12558c8d6ea9f388b54eb94ba6b9eb4a9fc5c9f2
+
+and it wasn't an issue before:
+https://github.com/moby/moby/commit/8c12a6648b368cc2acaea0339d6c57c920ed265c
+
+because it was using 'case "${GOARM}" in' and ${GOARM} was empty in our builds
+
