[PATCH] use bash instead of sh to run mkcompile_h

From: Liangcai Fan

From: Liangcai Fan <liangcai.fan@xxxxxxxxxx>

Use sh to run mkcompile_h, compilation would fail if whoami contains
backslash, since sh uses dash. The reason is that the echo command would
interpret backslash to escapes, so the LINUX_COMPILE_BY definition was
incorrect.

Parse mkcompile_h with bash, the echo command would not see backslash as
escapes, then there is no error with the definition of LINUX_COMPILE_BY.
