asm/system.h is quite commonly used in older telephony device drivers and
has been removed according to this commit to the kernel:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f05e798ad4c09255f590f5b2c00a7ca6c172f983
It looks it's some kind of hangover from days when serial devices were more
common and is therefore probably specific to some chipsets and it looks
like it's been regarded as being in the wrong place. You may have a better
chance building directly from source and either commenting out the #include
statement for it as it could be redundant or finding the last version of
the kernel that had it in, probably a late 3.3 release by the look of it
and putting the file in place so that the compiler can find it.
