Note you don't need --disable-mozilla any more. It is disabled be 
default (on master).

Can you check the place in output if ccache was correctly 
It sounds like you are compiling without ccache.
Try ccache -s to check if it is working correctly (in my case):
cache hit (direct)                 98667
cache size                            23.0 Gbytes
max cache size                    100.0 Gbytes

Also it may be needed to configure ccache, add something like this in 

# optionaly set CCACHE_DIR to second hard drive if you have one:
export CCACHE_DIR=/mnt/your_second_hard_drive
# set max cache size to 100 GB
ccache -M 100
