+Subject: [PATCH] Allow compiling xfsprogs in a cross compile environment.
+
+Without this patch, we are using the same compiler and options for the host
+compiler (BUILD_CC) and the target compiler (CC), and we would get error
+messages at compilation:
+x86_64-pc-linux-gnu-gcc -O2 -O2 -pipe -march=armv7-a -mtune=cortex-a15 ...
+x86_64-pc-linux-gnu-gcc.real: error: unrecognized command line option
+'-mfpu=neon'
+'-mfloat-abi=hard'
+'-clang-syntax'
+'-mfpu=neon'
+'-mfloat-abi=hard'
+'-clang-syntax'
+
+Add BUILD_CC and BUILD_CFLAGS as precious variables to allow setting it up
+from the ebuild.
