Not exactly. First, Debian does not use the default CC and CFLAGS
chosen by GMP (for a good reason I suppose, as it must at least
make sure that the chosen ABI for GMP is the same as the target
ABI). In the debian/rules file:

export CFLAGS = -Wall -g 

ifneq (,$(findstring noopt,$(DEB_BUILD_OPTIONS)))
  CFLAGS += -O0
else
  ifneq (,$(findstring $(DEB_HOST_ARCH), ia64))
    CFLAGS += -O2
  else
    CFLAGS += -O3
  endif
endif

CC   = $(DEB_HOST_GNU_TYPE)-gcc

Then, the GMP build/install process is something like:
  ./configure
  make
  make check
  make install

Copying gmp.h to another platform is not part of its process.
