Hm, this is getting annoying. :-) It looks like these are transitively pulled
in via libcompiler-rt:
0000000000063b70 <__kmpc_atomic_cmplx10_div>:
[...]
63c2d: e8 4e 50 03 00 callq 98c80 <__divxc3>
[...]
0000000000098c80 <__divxc3>:
[...]
98cb5: e8 86 14 00 00 callq 9a140 <fmaxl@plt>
98cba: db 3c 24 fstpt (%rsp)
98cbd: e8 8e 14 00 00 callq 9a150 <logbl@plt>
[...]
98d10: e8 4b 14 00 00 callq 9a160 <scalbnl@plt>
At some point, we'll have to get libgcc/compiler-rt users automagically pull in
-lm. Or fold libm into libc, like we should also do with libthr. ;-)
