+Disable the LDFLAGS "-Bsymbolic-functions" for mips
+
+"-Bsymbolic-functions" flag makes ld to bind the global function symbol of shared library at compiling time, thus reduce the runtime relocation cost.
+
+However, this flag in binutil 2.20 cause QT4 mips building failure, which is "final link failed: Bad value" error in libQtWebKit.so linking stage. If downgrad to binutil 2.19, this error disappears. further investigation showes commit http://sourceware.org/cgi-bin/cvsweb.cgi/src/ld/scripttempl/mips.sc.diff?r1=1.2&r2=1.3&cvsroot=src cause this error.
+
+So this patch disable this flag for QT4 mips. If future binutils version fix this issue, this patch can be safely removed.
