Subject: target/mips: Drop link syscall from semihosting
X-Git-Tag: v7.1.0-rc0~23^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3d748e41c759c7d207806b136be7694cfe2b6d65;p=thirdparty%2Fqemu.git

target/mips: Drop link syscall from semihosting

We don't implement it with _WIN32 hosts, and the syscall
is missing from the gdb remote file i/o interface.
Since we can't implement it universally, drop it.
