x86_64-pc-linux-gnu-gcc-5.4.0 -shared -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu -Wl,-z,defs [...] -L/usr/lib64 -lpython2.7 -o /tmp/portage/media-gfx/uniconvertor-2.0_pre379-r1/work/uniconvertor-2.0_pre379-python2_7/lib/uc2/formats/sk1/_sk1objs.so

/lib64/libm.so.6: error adding symbols: DSO missing from command line


To reproduce, use LDFLAGS='-Wl,-z,defs'. The error indicates that the module is using math functions from -lm but not linking to -lm. Normally, this goes unnoticed since Python implicitly links to -lm but it would still be good to avoid implicit linkage.
