Fakeroot significantly slows down builds (especially when ccache is enabled)

[joebonrichie]

Using curl as a test pkg

ccache?	Full ccache?	Fakeroot?	Time
no	N/A	yes	~15secs
no	N/A	no	~13secs
yes	no	yes	~25secs
yes	yes	yes	~13secs
yes	no	no	~17secs
yes	yes	no	~12secs

When building a slightly larger package such as glibc

ccache?	Full ccache?	Fakeroot?	Time
no	N/A	yes	~4mins
yes	no	yes	~13mins
yes	yes	yes	~3mins

We can see there is a huge penalty when fakeroot is enabled especially when the ccache cache is empty.

Need to explore options to getting rid of fakeroot most likely, the penalty is too large.
