broken poudriere with CCACHE

[Dmitry Morozovsky]

Dear colleagues,

10-stable at amd64

recently (coincident with pkg 1.8.3?) my poudriere starts failing with enabled 
ccache even with totally clean /var/db/ccache hierarchy. ports failing list 
begins with textproc/expat2 and ftp/curl, for example.

Failing message is

checking for gcc... cc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables...
checking whether we are cross compiling... no
checking for suffix of object files... configure: error: in 
`/wrkdirs/usr/ports/ftp/curl/work/curl-7.49.0':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details
===>  Script "configure" failed unexpectedly.

Disabling ccache support (can it be done in other way than commenting 
out CCACHE_DIR id poudriere.conf BTW?) helps

Any hints?
