Subject: Separate out CFLAGS for host builds and separate targets
X-Git-Tag: v0.0.106.0~2^2~4
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=faaa40d171accd037cfe6de2a0bda6f68a7eecbf;p=ldk-c-bindings

Separate out CFLAGS for host builds and separate targets

This should at least fix one bug someone ran into trying to build
for Android from OSX.
