+Subject: [PATCH] src/regex.c: support old compilers for the endian
+ check
+
+libselinux 2.6 has added some code in regex.c that uses __BYTE_ORDER__
+to determine the system endianness. Unfortunately, this definition
+provided directly by the compiler doesn't exist in older gcc versions
+such as gcc 4.4.
+
+In order to address this, this commit extends the logic to use
+<endian.h> definitions if __BYTE_ORDER__ is not provided by the
+compiler. This allows libselinux to build properly with gcc 4.4.

+Do not make symbols hidden on Blackfin
+
+The libselinux logic to hide internal symbols from the DSO doesn't
+work properly on Blackfin due to the USER_LABEL_PREFIX not being
+handled properly. A real fix is not that simple, so this patch simply
+disables the internal symbol hiding mechanism. This means that those
+symbols are visible in the final DSO, which is not a problem for
+proper execution, it just isn't as clean.

+fix undefined macros in musl
+
+musl does not define glibc-specific macros, so use a simple version of
+the macro when it is not defined.
+
+This is very inefficient, however, but copying the code from glibc is
+not really possible because it is LGPL while libselinux in Public
+Domain, and we want to avoid license propagation, so this macro is
+completely written from scratch, and non-optimal.
