Merge patches sent by Robert P. J. Day <rpjday@mindspring.com>.
Warning: the buildroot folks purposedly removed the skip-comment patch but didn't really said why. Keeping it for the sake of having it in svn just in case (removing it will be easier thant not having it at all).

3 comment "General toolchain options"
7 prompt "Use sysroot'ed toolchain"
10 Use the 'shinny new' sysroot feature of gcc: libraries split between
11 prefix/target/sys-root/lib and prefix/target/sys-root/usr/lib
13 You definitely want to say 'Y' here. Yes you do. I know you do. Say 'Y'.
17 prompt "Build shared libraries"
20 Say 'y' here, unless you don't want shared libraries.
22 You might not want shared librries if you're building for a target that
23 don't support it (maybe some nommu targets, for example, or bare metal).
25 config TARGET_MULTILIB
27 # prompt "Enable 'multilib' support (EXPERIMENTAL)"
30 Enable the so-called 'multilib' support.
32 With the same toolchain, and on some architectures, you will be able to
33 build big and little endian binaries, soft- and hard-float, etc...
35 See the gcc configure manual at http://gcc.gnu.org/install/configure.html
36 to see what multilib your target supports.
38 It's preferable for now to build two (or more) toolchains, one for each
39 configuration you need to support (eg. one for thumb and one for ARM,
40 etc...). You can use the vendor string to diferentiate those toolchains.
44 prompt "Vendor string"
47 Vendor part of the machine triplet.
49 A triplet is of the form arch-vendor-kernel-system.
50 You can set the second part, vendor, to whatever you see fit.
51 Use a single word, or use underscores "_" to separate words.
53 Keep the default (unkown) if you don't know better.
60 Normaly, you'd call your toolchain component (especially gcc) by
61 prefixing the target triplet followed by a dash and the component name
62 (eg. armeb-unknown-linux-uclibc-gcc).
64 You can enter a shortcut here. This string will be used to create
65 symbolic links to the toolchain tools (eg. if you enter "foo-bar" here,
66 then gcc for your toolchain will also be available as "foo-bar-gcc" along
67 with the original name).
69 You shouldn't need to enter anything here, unless you plan to manually
70 call the tools (autotools-based ./configure will use the standard name).

104 prompt "Canadian (EXPERIMENTAL)"
105 depends on EXPERIMENTAL
108 Build a canadian-toolchain.
109 See docs/overview.txt
115 prompt "Build system triplet"
118 Canonical name of the machine building the toolchain.
119 You should leave empty, unless you really now what you're doing.
126 The native C compiler.
128 You can set this to an alternative compiler if you have more than one
129 installed (eg. gcc is gcc-4.1.1 and you want to use gcc-3.4.6).
131 You can leave this empty as well, in which case gcc will be used.
135 prompt "Host system triplet"
137 depends on NATIVE || CANADIAN
139 Canonical name of the machine running the toolchain.
143 prompt "Cross-compiler prefix for host system"
144 default "${CT_HOST}-"
145 depends on NATIVE || CANADIAN
147 C compiler targeting the host system.
151 prompt "Cross-compiler prefix for target system"
152 default "${CT_TARGET}-"
155 C compiler targeting the target system.
