Description:
static bin/mysql still loads dynamic libraries from system, and if there're any incompatibilities, it would crash. for example history browsing in Asianux crashes with ISO8859-1.so

Example:

open("/usr/lib/gconv/gconv-modules.cache", O_RDONLY) = 4
fstat64(4, {st_mode=S_IFREG|0644, st_size=21544, ...}) = 0
mmap2(NULL, 21544, PROT_READ, MAP_SHARED, 4, 0) = 0xb7d48000
close(4)                                = 0
futex(0x88514c, FUTEX_WAKE, 2147483647) = 0
open("/usr/lib/gconv/ISO8859-1.so", O_RDONLY) = 4
read(4, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\20\4\0"..., 512) = 512

How to repeat:
export LANG=en_US, do some readline activity

Suggested fix:
do not load shared modules or have them inside static binary.

Closing as "won't fix", because this bug is targeted for 6.0, and we don't support static builds in 6.0.
