Undefined reference to egl and gl issue

When I migrated my project to cargo-apk from the current dev branch, I ran into this problem.

Test project:
cargo-apk-repro-case.zip

Output:

This is likely the same as #230 and is caused by a regression in the build system. The fix is waiting to be merged #232. Do you mind trying it with the branch that is waiting to be merged?

@Nirklav @mb64 FYI. I was able to build using #232.

@philip-alldredge, i was able to build my project too, with this branch, thanks!

[philip-alldredge]
