It's the checkout of
git://github.com/janneke/gub.git

Searching the web and the mailing lists a bit more revealed that there is an 
undocumented environment variable, which one can use to force a given ABI:

ABI=32 make lilypond

It's not ideal that gmp doesn't detect this automatically, but at least now it 
builds correctly.


However, I'm now running into the next problem:  Lilypond's configure claims it 
is missing guile!

Here's the output:
[...]

Strange enough, on that same machine the nightly binary and docs builds work 
fine and detect guile just fine... The configure output of the current git 
master 
(using the system-wide installed guile) is:
[...]
checking for guile-config... guile-config
checking guile-config version... 1.8.5
checking guile compile flags...   -pthread

[...]
checking for guile... guile

So, apparently the guile built by gub is missing scm_boot_guile or some link 
flag....

Cheers,
Reinhold
