termux_step_massage: check built libs for undefined symbols
Building packages that use libtool for linking libraries has issues
with ndk-r23 (https://github.com/android/ndk/issues/1614).  This check
makes sure that the built libraries do not give an error like

    CANNOT LINK EXECUTABLE "tesseract": cannot locate symbol "__extenddftf2" referenced by "/data/data/com.termux/files/usr/lib/libtesseract.so"...

once used on device.  In https://github.com/android/ndk/issues/1614 it
seemed like arm gave false positives and needed special consideration,
but when I tested it again today the same false positives do not occur
in built libraries, so no "if arm then .." workaround has been added
for now.
