GMP does not build if the host gcc is v4.9 due to the following error
gen-sieve.c: In function 'setmask':
gen-sieve.c:99:3: error: 'for' loop initial declarations are only allowed in C99 or C11 mode
for (unsigned i = 0; i < 2 * a * b; ++i)
^
gen-sieve.c:99:3: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 to compile your code
The gen-sieve utility was added in GMP v6.3.0. It is built using
CC_FOR_BUILD (host compiler) during cross compilation as it generates
build files. Autoconf does not have a macro for add -std=c99 to
CC_FOR_BUILD, so it must be set manually. For the target, it is set
correctly thanks to the AC_PROG_CC_C99 macro.
