NDK r25 has removed GNU Assembler (GAS). Removal of GAS introduced a number of build issues.
The most prominent is:
/usr/bin/as: unrecognized option '-EL'
Some options to solve this:
1. Disable building custom assembly and suffer performance penalty
2. Hand rewrite the custom assembly to be LLVM compatible
3. Wait for upstream to write LLVM compatible assembly (openssl, openssl-1.1)
4. Bring back GAS from NDK r23c
In this commit, GAS is brought back as a separate toolchain instead of following NDK r23c file hierarchy.
We pass "--gcc-toolchain=GAS_TOOLCHAIN_DIR" to NDK r25 clang to detect.
Packages only have to add "termux_step_gnu_as_23c" to build.sh to enable GAS.
In the future, we expect packages should follow option 3 more than option 4 as that is a last resort.
This commit also bumps revision for packages that rely (or previously rely) on "-fno-integrated-as":
hors, libffi, libgcrypt, libpixman, openssl, openssl-1.1
