Bugzilla Bug 71295

./config/imake/imake -I./config/cf  -s ./config/makedepend/Makefile.proto -f
./config/makedepend/Imakefile -DTOPDIR=../.. -DCURDIR=./config/makedepend
sh: /tmp/imakeKkK4Lf: Permission denied
make[1]: *** [config/makedepend/Makefile.proto] Aborted

`/usr/local/tmp/portage/vnc-4.0/work/vnc-4.0-unixsrc/xc'
make: *** [World] Error 2


For security reasons, many users have /tmp mounted with noexec to prevent some
hacks.  This keeps the ebuild from installing since imake tries to use tmp to
run a script it makes.  

Solution, change /tmp to portage temp directory.

Reproducible: Always
Steps to Reproduce:
1. mount /tmp with -o noexec
2. emerge vnc-4.0

Actual Results:  
sh: /tmp/imakeKkK4Lf: Permission denied


Expected Results:  
merged vnc
