26# that generates machine code that will run properly on Ubuntu 8.04 (Hardy)
27# By default, the code generated by the Lucid host toolchain will not run
28# on previous versions of the platform, due to GLibc ABI mistmatches
29# (Lucid is 2.11, Hardy is 2.7)

32# which is loaded by the 64-bit JVM through JNI), will have to use
33# LOCAL_CC and LOCAL_CXX to override this.
