* Don't strip debug info on Darwin, otherwise links by libtool fail

("/usr/bin/ld: can't use -s with -r (resulting file would not be
  relocatable)").
* Since stdenv/generic had to be modified for this, I forked it in
  situ.  This should be merged later.

* genericBuild performs a generic build of (typically) autotool-style
packages
* unpack phase
** may be overriden by setting $unpackPhase to point at a function that
unpacks the source (which should set $sourceRoot)
** the generic unpacker unpacks all sources specified by $srcs, or
$src if $srcs is empty
** supports tar, bzipped tar, gzipped tar, compressed tar, zip
** zip must be in scope (in $buildinputs)
** additional file types may be supported by setting $findUnpacker,
which is called with a single argument specifying the file to be
unpacked
** $findUnpacker should set $unpackCmd, specifying the full command to
unpack the file (must include the file name)
** alternatively, $unpackCmd can be set before calling the generic
builder (e.g., 'unpackCmd="unrar x $src"'); this only works if
there is a single source file
** the generic unpacker then sets $sourceRoot to the name of the
directory created by unpacking the source archives
** the source archives should produce only one directory
** alternatively, $setSourceRoot may be set to a function that sets
$sourceRoot
* the generic builder then chdirs to $sourceRoot
* patch phase (skipped if neither $patchPhase nor $patches are set)
** may be overriden by setting $patchPhase to point at a function that
unpacks the source (which should set $sourceRoot)
** if the $patches variable is set, it runs `patch -p1 < ...' in
$sourceRoot for each element in $patches (the `patch' command
should be in $PATH; note that it isn't in the standard environment)
* configuration phase
** may be overriden by setting $configurePhase to point at a function
** calls $preConfigurer first, if set (useful for running
autoconf/automake)
** the configure script is specified by $configureScript, which
defaults to ./configure
** if no executable file exists at $configureScript, does nothing
** if a file ./ltmain.sh exists and $dontFixLibtool is not set, calls
function fixLibtool to remove its default search path (/usr etc.)
** adds "--prefix=$out" to $configureFlags unless $dontAddPrefix is
set
** calls $configureScript with $configureFlags
** calls $postConfigurer, if set (useful for any last-minute patches
prior to building)
* build phase
** may be overriden by setting $buildPhase to point at a function
** runs make with flags $makeFlags
* install phase
** may be overriden by setting $installPhase to point at a function
** runs make with flags $installFlags
** unless $dontStrip is set or $NIX_STRIP_DEBUG is not 1, finds all *.a
files in $out and runs "strip -S" on them (executables and dynamic
libraries can be stripped automatically by setting NIX_STRIP_DEBUG
to 1 (default))
** if $propagatedBuildInputs is set, its contents are written to
$out/nix-support/propagated-build-inputs
