[oe] [meta-oe][PATCH] mozjs: customize HOST_CFLAGS

[jackie.huang at windriver.com]

From: Mingli Yu <Mingli.Yu at windriver.com>

Customize HOST_CFLAGS, HOST_CXXFLAGS and HOST_LDFLAGS
to fix do_configure error as previously use the common
CFLAGS and CXXFLAGS in both cross-compile env and host env,
and the option -fstack-protector-strong which not
recognized in host env can result in do_configure
error as below.

| checking whether the host c compiler (gcc -O2 -pipe -g -fstack-protector-strong -D_FORTIFY_SOURCE=2 -Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed -fstack-protector-strong -Wl,-z,relro,-z,now) works... configure: error: installation or configuration problem: host compiler gcc cannot create executables.
