Attempting to upgrade to media-plugins/alsa-plugins-1.0.19, build repeatably fails with the linker reporting broken references to "floor", "sin", etc. This is a canonical example of missing libm in the linker chain.

Ugh, that's too big. Figuring out how to edit the damn thing...
If I say USE="-speex", it emerges correctly. The problem is thus isolated to the speex support. I see there's already a bug about a different aspect of that.

Just from preliminarily looking at it, I think the cause is that resample.c is not being linked with -lm
in a "works for me" kinda approach ( I use speex in my system, wanted my plugins to build with it ) I did the following: sed -i 's/speex_LIBS: $speex_LIBS/speex_LIBS: $speex_LIBS -lm/g' configure in the ebuild, in src_prepare section. This permits alsa-plugins 1.0.19 to build with USE=speex on. Probably NOT the best way to do this, and likely horribly b0rken, but works for me.
3rd "me too" - broke for me too, and "-speex" worked around the problem

Shouldn't this be sent upstream though? I reported this ages ago and there's been no concrete activity.
A patch has been added to alsa 1.0.19, please remerge and test. 1.0.20 should be unaffected, too.
