 -------
 
 As of -current 20210629, ./build.sh will build src on OpenBSD 6.9
-for some platforms. Known problems:
-* MIPS targets do not currently build. 
-* The LLVM RT library will not build and consequently nor will X on 
-  amd64 and i386.
+for all targets except MIPS-based ones. 
+
+For builds requiring the LLVM RT library (including X on amd64, 
+i386 and evbarm64-el), the build user's limits needs to be setup 
+for higher memory usage, otherwise the build will fail. This can
+be achieved by either building as root (not recommended) or
+by changing the datasize attribute to infinity for the relevant
+groups and users in /etc/login.conf.
