Subject: [build] Fixed build break for OCaml bindings.
X-Git-Tag: android-x86-7.1-r4~31443
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=38ae857b162884ccd7b16933967bdf7a634e6006;p=android-x86%2Fexternal-llvm.git

[build] Fixed build break for OCaml bindings.

After r273302 LLVM_SYSTEM_LIBS may have entries that already have
-l prefix and we need to deal with that.
