+Subject: [PATCH 1/1] configure: fix cross-compilation issues
+
+- Use CFLAGS from command line
+
+- Remove "Check C compiler type (optimization options)"
+ This test force optimization to -O3
+ while it is already set in CFLAGS
+
+- Don't use host CPP
+
+- Remove "Check for Large File Support"
+ LFS support is already set in CFLAGS
+
+Note: configure script still use host nm
+
