It's time to finally switch over globally to the new spacing format
that we have agreed on for the hash file, with 2 spaces as a separator
between fields.
This commit was mechanically generated using:
find . -type f -name '*.hash' | xargs sed -i 's%^md5[ \t]*\([^ \t]*\)[ \t]*\(.*\)$%md5 \1 \2%'
find . -type f -name '*.hash' | xargs sed -i 's%^sha1[ \t]*\([^ \t]*\)[ \t]*\(.*\)$%sha1 \1 \2%'
find . -type f -name '*.hash' | xargs sed -i 's%^sha256[ \t]*\([^ \t]*\)[ \t]*\(.*\)$%sha256 \1 \2%'
find . -type f -name '*.hash' | xargs sed -i 's%^sha512[ \t]*\([^ \t]*\)[ \t]*\(.*\)$%sha512 \1 \2%'
This commit can easily be backported on the LTS branch by re-running
the same commands, if needed.

Currently, building czmq statically fails for some architectures with undefined
references to the math library:
/usr/powerpc-buildroot-linux-uclibc/sysroot/usr/lib/libstdc++.a(compatibility-ldbl.o): In function `std::tr1::hash<long double>::operator()(long double) const':
compatibility-ldbl.cc:(.text._ZNKSt3tr14hashIeEclEe+0x3c): undefined reference to `frexpl'
It turns out that this is actually a problem with libstdc++. Depending on the
arch, some functions will be in compatibility-ldbl.o. If you use any of these
functions, that file will be linked in. And when that file is linked in, all
the _other_ functions, which you actually don't use, are also linked in. And
one of these functions is the template function hash<long double>::operator(),
which uses frexpl.
Requiring czmq to link with -lm is a bit weird, given that neither itself,
nor any of its dependencies really need it...
So ideally it should be fixed in libstdc++ itself. However, as upstream
accepted a patch to link with -lm, we use this patch to fix static linking.
