 Description   

10.5 fails to build on Debian 9:
"undefined reference to symbol '__bss_start' /usr/lib/x86_64-linux-gnu/libgmp.so.10:
error adding symbols: DSO missing from command line "

The issue was fixed in 10.2 but not merged to 10.5 (MDEV-10943):
Linux does not actually use bss_start;
Put bss_start into #ifndef _linux_ section.

MDEV-23491 was filed for this a little earlier, suggesting that we just let the kernel’s write() system call validate the pointer. I think that this issue was caused by MDEV-15961. We saw some breakage on various platforms.
