just tried updating to uclibc-ng 1.0.27 and now I get the following

This is because I have DO_XSI_MATH disabled and commit
ea38f4d89c9698895b1cf53a5946429dc1d8bbaa added a lot of files to compile
unconditionally that use functions only enabled with DO_XSI_MATH.
Thanks for the bug report Ronald.
Sergey, you contributed the math rework patch, could you have a
look?
Conditionally compiling the files
w_j0.c w_j0f.c w_j0l.c
w_j1.c w_j1f.c w_j1l.c
w_jn.c w_jnf.c w_jnl.c
seems to be enough. Not sure if DO_C99_MATH needs to be set as well.
DO_XSI_MATH and DO_C99_MATH do not depend on each other.
