  This is a bug of the current mercurial repo in the tune/ directory:
  When I run `make -j6 allprogs` for the first time, an error was emitted:
  libtool: link: (cd .libs/libspeed.lax/libtests.a && ar x "/data/data/com.termux/files/home/gmp-unstable/tune/../tests/.libs/libtests.a")
  libtool:   error: cannot find the library '' or unhandled argument ''
  make: *** [Makefile:626: tune-gcd-p] Error 1
  The error will not be emitted when I invoke the above command for the second time. How to fix this? Thanks!

Parallel build in the tune subdir are not supported.  Please build
normally therein.
