This reverts commit 0a944b345e, reversing
changes made to 61733ed6cc.
I dislike these massive stdenv changes with unclear motivation,
especially when they involve gratuitous mass renames like NIX_CC ->
NIX_BINUTILS. The previous such rename (NIX_GCC -> NIX_CC) caused
months of pain, so let's not do that again.
(cherry picked from commit ec8d41f08c)
The $lib output refers to the terminfo database in $out, which is about
10x larger than the ncurses shared library. Splitting these outputs
saves a small amount of space for any derivations that use the terminfo
database but not the ncurses library, but we do not have evidence that
any such exist.
Sourcery CodeBench manpages are installed under
share/doc/<target-triplet>/man/. Add symlinks so that the manpages
become available to "man".
NOTE: I use symlinks instead of moving the manpages, because I think
it is best to do as little as possible to prebuilt packages.
Sourcery CodeBench toolchains are prebuilt GCC toolchains from Mentor
Graphics.
Start out by adding ARM EABI and ARM GNU/Linux toolchains. Sourcery
CodeBench is also available for MIPS, Power, SuperH, ColdFire (and
more), so it should be easy to add later, if needed.
AFAIK, the EABI toolchains use newlib and the GNU/Linux ones use glibc.
