gcc49 from pkgsrc

[BERTRAND Joël <joel.bertrand%systella.fr@localhost>]

	Hello,

	I'm trying to build gcc 4.9.2 from pkgsrc on a raspberry PI B+. 
Compilation fails with :

c++   -g -DIN_GCC    -fno-exceptions -fno-rtti 
-fasynchronous-unwind-tables -W
-Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format

`host_detect_local_cpu(int, char
const**)'
Makefile:1805: recipe for target 'xgcc' failed
gmake[3]: *** [xgcc] Error 1

	I haven't found any usable workaround but some users seem to have the 
same issue. Do you have idea to build gcc 4.9.2 on arm ?

	Best regards,

	JB
