libraw: add patch to remove Byte order mark

This Byte order mark is not recognized by gcc < 4.4, which is the case
on Blackfin where gcc 4.3.x is used. Since this BOM is not useful
anyway, we simply remove it. The patch has been submitted upstream.

+Subject: [PATCH] libraw_x3f.cpp: remove Byte order mark
+
+The U+FEFF character, which is a Byte order mark, at the beginning of
+libraw_x3f.cpp, prevents gcc 4.3.x from building this file:
+
+src/../internal/libraw_x3f.cpp:1: error: stray '\357' in program
+src/../internal/libraw_x3f.cpp:1: error: stray '\273' in program
+src/../internal/libraw_x3f.cpp:1: error: stray '\277' in program
+
+Support in gcc for the Byte order mark has been added in gcc
+4.4.x. Since anyway this Byte order mark is not useful, we simply
+remove it.
+
+See https://en.wikipedia.org/wiki/Byte_order_mark for more details.
