The libm gamma functions use the _gamma_signgam field of the reentrant structure, which changes offset with the --enable-newlib-reent-small configure option, which means we need to use a newlib nano specific version of libm in addition to libc in the nano.specs file. Reported by Keith Packard. There is a riscv-gnu-toolchain patch that goes along with this to create the new libm_nano.a file.
