+Known issues
+============
+
+* The +ltp-testsuite+ package does not build with the default uClibc
+ configuration used by the Buildroot toolchain backend. The LTP
+ testsuite uses several functions that are considered obsolete, such
+ as sigset() and others. uClibc configuration options such as
+ DO_XSI_MATH, UCLIBC_HAS_OBSOLETE_BSD_SIGNAL and
+ UCLIBC_SV4_DEPRECATED are needed if one wants to build the
+ +ltp-testsuite+ package with uClibc. You need to either use a glibc
+ or eglibc based toolchain, or enable the appropriate options in the
+ uClibc configuration.
+
+* The +xfsprogs+ package does not build with the default uClibc
+ configuration used by the Buildroot toolchain backend. You need to
+ either use a glibc or eglibc based toolchain, or enable the
+ appropriate options in the uClibc configuration.
+
+* The +mrouted+ package does not build with the default uClibc
+ configuration used by the Buildroot toolchain backend. You need to
+ either use a glibc or eglibc based toolchain, or enable the
+ appropriate options in the uClibc configuration.
+
+* The +libffi+ package is not supported on the SuperH 2 and ARC
+ architectures.
+
+* The +prboom+ package triggers a compiler failure with the SuperH 4
+ compiler from Soucery CodeBench, version 2012.09.
