+Subject: efi/libstub: arm: support building with clang
+
+From: Alistair Strachan <astrachan@google.com>
+
+commit 41f1c48420709470c51ee0e54b6fb28b956bb4e0 upstream.
+
+When building with CONFIG_EFI and CONFIG_EFI_STUB on ARM, the libstub
+Makefile would use -mno-single-pic-base without checking it was
+supported by the compiler. As the ARM (32-bit) clang backend does not
+support this flag, the build would fail.
+
+This changes the Makefile to check the compiler's support for
+-mno-single-pic-base before using it, similar to c1c386681bd7 ("ARM:
+8767/1: add support for building ARM kernel with clang").
