space.inline.hpp build failure

[Peter Johnson]

When cross compiling either 9 or 10 to ARM with gcc 5.5.0, I get the
following linker error:
/tmp/cc7TKVtK.ltrans2.ltrans.o: In function
`OffsetTableContigSpace::block_start_const(void const*) const':
<artificial>:(.text+0x26e4): undefined reference to
`BlockOffsetTable::block_start(void const*) const'
/tmp/cc7TKVtK.ltrans13.ltrans.o: In function
`OffsetTableContigSpace::verify() const':
<artificial>:(.text+0x2ca6): undefined reference to
`BlockOffsetTable::block_start(void const*) const'
collect2: error: ld returned 1 exit status

This appears to be due to a missing include in space.inline.hpp.  Applying
the following patch fixes the build for me.

Thanks,
Peter
