-\fB\-\-x86\fR
-One oddity of the x86 toolchain is that they may be named 'i386', or 'i486', 
-or 'i586', or 'i686', yet still produce the same exact code.  When dealing 
-with distcc systems that are mixed (some i586 and some i686), you will need 
-symlinks for all these targets.  This option will install those extra targets.
-.TP
 \fB\-\-amd64\fR
 A nice feature of the amd64/x86 toolchain is that each can produce code for 
 other.  The typical user could care less, but some may want to be able to 
 cross-compile for an amd64 on a x86 system.  This will install the extra 
 symlinks ('x86_64') to facilitate this process.
+.TP
+\fB\-\-arm\fR
+The arm architecture comes in both big and little endian versions.  Typically 
+you only need support for the native target, but sometimes it's helpful to 
+have links for the other endian target.  This will make sure you have both the 
+big endian target ('armeb') and the little endian target ('arm').

+The mips architecture (like arm) comes in both big and little endian versions.  
+Typically you only need support for the native target, but sometimes it's
