[Qemu-devel] [PATCH v3 0/3] buildsys: Move crypto libraries to per object variables

[Qemu-devel] [PATCH v3 0/3] buildsys: Move crypto libraries to per object variables

[Fam Zheng]

v3: Remove one more line that was missed in v2.

Not all targets need the flags and libs of gcrypt/nettle/gnutls, so move them
out from global variables, as done with other libraries.

There are still other libraries in ./configure that can be converted this way,
which will be sent separatedly.

Fam Zheng (3):
  buildsys: Move nettle cflags/libs to per object
  buildsys: Move gnutls cflags/libs to per object
  buildsys: Move gcrypt cflags/libs to per object

This is a bit ugly, but i don't see any obvious alternative that
would work
