The Xtensa gcc does not seem to like output on /dev/null. The applied patch on dhcpcd is thus unusable, and a more verbose version involving a temporary file is needed.

configure: support builds using ccache
|
|
|
|
The configure script checks whether CC is executable by means of a check
|
|
'type $CC'. However, when using ccache, CC is normally set to "ccache gcc"
|
|
(using the appropriate paths). Such a compound string is not recognized by
|
|
type, however, and thus configure bails out.
|
|
|
|
This patch changes the check 'type $CC' with a compile test.

Note: a simplification of this patch was accepted upstream, but turns out to be
|
|
non-usable by the Xtensa architecture. This was also reported upstream and
|
|
should normally be reverted soon.
