This patch backports the makefile changes related to the support/
|
|
|
ce426f |
framework. It is based on upstream commits
|
|
|
ce426f |
c23de0aacbeaa7a091609b35764bed931475a16d (support: Introduce new
|
|
|
ce426f |
subdirectory for test infrastructure) and
|
|
|
ce426f |
76dcbf42df83c970c13c786d287f1ec69e1b91eb (Expose linking against
|
|
|
ce426f |
libsupport as make dependency).
|
|
|
ce426f |
|
|
|
ce426f |
The actual contents of the support/ subdirectory is kept in a separate
|
|
|
ce426f |
patch, so that it can be updated separately.
