TCL,
I never got gsi to compile on android but it isn't needed to run scheme on android. To rid of the errors you might want to edit the
makefile.in in the gambit package to not build gsi
Change line 73:
SUBDIRS = include lib gsi gsc bin misc doc tests examples contrib prebuilt
To:
SUBDIRS = include lib gsc bin misc doc tests examples contrib prebuilt
you might have to remove some of the other items as well if they don't compile. I haven't tested this and I'm not sure if it will work but hopefully it will point you in the right direction.
