It seems to related to the toolchain where __ELF__ is not defined.

checking whether system is ELF... no

Then shared lib libgpm.so.2 is not build but still used in Makefile's 
target all...

I'm not sure about the right solution here but force the ELF format in 
gpm.mk fixe the build.
GPM_CONF_OPT += itz_cv_sys_elf=yes
