libgcrypt.inc: Fix libgcrypt compilation with GCC-4.4 on mips
Patch taken from https://forum.openwrt.org/viewtopic.php?id=20520
Makes sense and seems to work ok.
libgcrypt.inc has --disable-asm in EXTRA_OECONF, yet strangely the configure
script does nothing with this information beyond parsing it. Assembler is
certainly still being used.
