What is the intended way of using this? Do you run make with
`LIBPTHREAD=-pthread` or do you apply a patch on `libraries.m4` for the
specific way of linking to pthread?
make/autoconf/libraries.m4 line 142:

If you specifically need this to be resolved in the makefile rather than here,
then please add a comment explaining why, otherwise use a shell script variable
reference.
Suggestion:
BASIC_JVM_LIBS="$BASIC_JVM_LIBS $LIBPTHREAD"
