Building Mono Without Bash: Syntax Error in doltlibtool - bash

Question

I'm building mono on an android device and getting an error when the build runs ./doltlibtool
make[4]: Entering directory `/bld/mono/mono-4.0.0/eglib/src'
CC libeglib_la-garray.lo
../doltlibtool: line 4: syntax error: unexpected "("
Here is line 4 of doltlibtool:
1 #!/bin/bash
2 top_builddir_slash="${0%%doltlibtool}"
3 : ${top_builddir_slash:=./}
4 args=()
5 modeok=false
6 tagok=false
From what I can tell, the problem is due to the fact that I'm not using bash. Is there any way to fix this without building and using bash?
CORRECTION
I am using bash...but the busybox version of bash, which isn't really bash and so does not support arrays.

Answer 1

From the mono-devel mailing list, to which I posted the question:
Is it possible to build mono without bash?
It is unlikely.
Your best bet is to cross compile.
Shells that do not handle arrays (like the default Android shell or the default shell in KBOX...which is a busybox version of bash) cannot be used when compiling mono 4.0.0. Specifically the line
args=()
will throw an error.
I ended up downloading the bash source and building it before trying to build mono
