Subject: Makefile.uk: Allow configuring with custom config file
X-Git-Tag: RELEASE-0.14.0~8
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=6a2ee037e14deaafd08a9ab9462e2e955469ea22;p=unikraft%2Flibs%2Fpython3.git

Makefile.uk: Allow configuring with custom config file

The `.config.orig` rule does a backup of the config file before changing
it to set `CONFIG_STACK_SIZE_PAGE_ORDER=10`. This used a hardcoded path
to the default `.config` file instead of `$(C)`, which can be set to a
custom one.

Using a hardcoded path will fail if trying to build with a different
config file than the default one (i.e. using `make C=path-to-config`).
One of the usecases is `kraftkit`, which uses `.config.python3...`
instead of the default `.config` file.
