Hmm, when I try exporting CFLAGS="-g -O2 -fsanitize=address" and then
run configure, it pauses and then fails on the cross-compiling check:

[...]
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... configure: error: in 
`/home/ben/NANO':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details


In config.log there are seven thousand lines of this:
==12567== AddressSanitizer CHECK failed: 
../../../../src/libsanitizer/sanitizer_common/sanitizer_linux.cc:309 
"((proc_self_maps_.len)) > ((0))" (0x0, 0x0)

and then:

./configure: line 3493: 12567 Segmentation fault      ./conftest$ac_cv_exeext

$ gcc --version | head -1
gcc (Ubuntu/Linaro 4.8.1-10ubuntu9) 4.8.1
